The movie opens in 1968 at the height of the Vietnam War. A platoon of American troops pushes through the jungle under pouring rain. Their sergeant tries to reach support through the radio and mentions how many men he has already lost. Tension spikes when a soldier lets out a scream and vanishes into the darkness, throwing the unit into chaos. The sergeant fires into the shadows, hoping to hit whatever took his man, but the real threat steps out of the trees. A massive dinosaur bursts from the foliage and charges at him with terrifying force.

The next morning, two army officials reach a small village in Vietnam where a group of American soldiers has established a temporary camp. They are there to look into a shipment of nuclear material that the Soviets are believed to be using somewhere in the area.

A distressed woman quickly approaches them and tries to explain that a feathered demon took her husband’s life. The officials brush off her story, convinced that she is simply overwhelmed by fear and grief.

The two officials explore the nearby terrain and quickly discover that radiation levels are unusually high. They meet a colonel named Jericho and brief him on what they found, along with the fact that their own team vanished in a valley not far from the camp. Jericho decides to deploy his unit known as Vulture Squad to search for the missing group.

He later gathers the squad, a group of seasoned soldiers who are accustomed to high risk assignments. Jericho explains that an entire platoon disappeared deep inside a remote valley and their task is to locate them. The men have heard whispers about strange activity in that area, but when they press for answers, Jericho cuts them off and says the details are classified.

We are then introduced to the members of Vulture Squad, with Sergeant First Class Baker serving as their leader. His second in command is Sergeant Xavier, and their newest addition is Leon, a young radio operator still trying to find his footing. The rest of the team consists of former Air Cavalry soldiers Eli and Miller, along with the squad’s two sharpshooters, Keyes and Logan.

That night, helicopters carry Vulture Squad deep into the jungle and drop them into the thick wetlands below. The pilot gives one last warning that the compass cannot be trusted because of heavy magnetic interference in the region. Even so, the team touches down on the soggy ground and pushes forward.

Before long, they spot huge claw marks carved into the trees and enormous three toed tracks pressed into the mud, signs that something massive passed through. They also find a discarded backpack with a map of Research Station 4 tucked inside, along with a notebook containing a chilling message that reads, “We are being hunted.”

The squad studies the map and agrees to follow the route marked on it. In the middle of their discussion, a dinosaur lunges out of the brush and yanks Baker into the trees. He manages to steady himself and unleashes a burst of gunfire, startling the creature enough that it retreats back into the darkness.

The story shifts to another section of the valley, where a unit of Soviet soldiers is conducting a patrol. They are being led by a local woman named Con Nhen, who holds deep resentment toward the Americans after losing her family and her village to their attacks. The group advances with caution, but one soldier drifts too far from the others. A dinosaur bursts from the foliage and kills him instantly, ripping off his head in one bite. When the rest of the patrol finds his remains, they assume the Americans are responsible and swear they will strike back.

Meanwhile, Vulture Squad reaches a cave and finds the mangled remains of the missing soldiers. The sight overwhelms them, and the condition of the bodies makes it clear that something terrifying took place there. Without warning, a group of large feathered dinosaurs bursts out of the shadows and charges at them. The squad opens fire with everything they have, struggling to grasp how creatures from another age could possibly exist.

A moment later, an enormous dinosaur bursts through the area and crushes the trees around it as it charges forward. The chaos splits the squad apart, leaving Baker and Leon stranded and unable to find the others. They scramble up a set of heavy vines to get away from the creature and eventually reach the top of the cave. Once they pull themselves over the edge, they freeze. A sleeping T Rex rests only a short distance away, and the sight nearly stops their hearts. They try to retreat quietly, but a cluster of young hatchlings wanders out and lets out sharp cries that echo through the cavern, waking their mother.

The mother T-Rex snaps awake and immediately turns her fury toward the intruders. Baker and Leon open fire, yet the rounds barely even slow her down. They sprint through the dense growth while the massive predator barrels after them with unbroken determination. Out of options, they slip behind a thick patch of bushes and try to stay out of sight, though the T Rex soon begins closing in on their hiding spot with a deep, rumbling growl.

By morning comes, the five remaining soldiers manage to push their way out of the thick jungle. Miller argues that they need to head back and search for Baker and Leon, but Eli refuses and insists they should request emergency support immediately. Miller reminds him that the only radio is with Leon, leaving the group stranded without any means to reach the outside world.

Somewhere else, Baker and Leon are still running for their lives when they reach a cliff that drops straight down to a river. With no other escape, they leap into the water, and the furious T Rex hurls itself in right behind them. The massive splash sends tremors through the valley, and Leon blacks out from the impact. Baker pulls him to the shore and the two slip away as quietly as they can, keeping just far enough ahead of the creature to survive.

Out of nowhere, a Russian woman emerges from the trees and introduces herself as Sofia. She helps Baker lift Leon from the water, and Baker quickly notices that she seems to understand these dinosaurs far better than anyone he has met so far. Sofia offers to take them to a safe place she has set up nearby. Baker hesitates, unsure if he should trust her, but with no real alternatives, he decides to follow her.

Meanwhile, the remaining members of Vulture Squad keep moving through another part of the valley as they continue searching for Baker and Leon. Along the way, they come across a group of dinosaurs again, but this time the creatures show no aggression. They are plant eaters and simply watch the soldiers pass without posing any threat.

Some distance away, Sofia guides Baker and Leon to an outpost known as Research Station 4, a facility where she has survived on her own for the past year. She explains that she is a paleontologist and that everything happening in the valley is connected to a Soviet project overseen by a general named Borodin. As she talks, she injects morphine into her arm, a quiet admission that isolation in a place like this has worn her down and pushed her into addiction.

Leon eventually manages to reach the base, and Baker gets on the line with Colonel Jericho, furious about everything that has happened. He explains the situation with the dinosaurs and tells Jericho to look into a Russian general named Borodin, who is responsible for this entire operation. Jericho refuses to believe that living dinosaurs could exist, though he does agree to have his team investigate Borodin. Baker snaps back, accusing him of sending the squad in without the information they needed, then orders him to send a helicopter to extract them before nightfall.

After the call ends, the three of them leave the facility to track down the rest of the squad so they can make their way out of the valley. In another part of the area, Vulture Squad moves across an open field when Soviet snipers suddenly open fire, and Keyes takes a hit to the leg. Both sides dive for cover and unleash shot after shot, their firefight so loud it draws a swarm of flying dinosaurs.

The creatures swoop down and attack without hesitation, forcing the Americans and Soviets to fight side by side. One of the dinosaurs grabs a Soviet soldier and tears him apart, and the entire flock rushes in to feed. The soldiers use that moment of chaos to break away and escape.

Later, while the squad is treating Keyes in the woods, they finally run into Baker and Leon, who are accompanied by Sofia. The reunion is brief, because another wave of dinosaurs bursts through the trees and charges at them. The team opens fire in every direction, yet one of the creatures slips past the barrage and lunges at Keyes.

Keyes is already weak from his earlier wound and assumes he will not survive, but he manages to grab his knife and drive it into the dinosaur’s neck. The creature releases a piercing scream that alerts the others, and the rest of the squad quickly turns their weapons on it. Under the hail of gunfire, the dinosaur backs off and eventually retreats into the forest.

The group rushes Keyes back to the research station and does what they can to stabilize him. They give him morphine to dull the pain, but Sofia soon takes a dose for herself and slips into another room. Baker follows after her and confronts her about what she is doing. Worn down and frustrated, Sofia admits that everything happening in the valley began with a mistake.

She explains that Borodin had planned to open wormholes that would allow him to teleport into the United States and destroy it from the inside. The experiment spiraled out of control when the collider pushed particles beyond the speed of light, which opened a rift connecting the present to the Cretaceous era. Dinosaurs flooded into the valley while the war was still raging. Sofia’s husband and the rest of the scientific team tried to stop Borodin, but he had them killed. He then moved the project to a new site, where he continues trying to force the wormhole open again.

Without warning, the walls start to shake as the dinosaurs that have been tracking them launch an assault on the research station. The squad fires through every window and doorway they can reach, but the attack only grows more intense. A massive dinosaur eventually crashes straight through the main entrance and forces its way inside.

In the chaos, Sofia tells them there is a boat tied up on the nearby river, but its engine is dead and she has no way to repair it. She insists the soldiers might be able to get it running and urges them to use it as their way out of the station.

The group gets ready to run, but Keyes understands he will not make it out and tells them to go without him. His teammates share a final, painful goodbye before leaving the facility behind. Once they are gone, Keyes smiles to himself and triggers the explosives he had carried in. The blast tears through the station and wipes out many of the dinosaurs inside.

Out by the river, the rest of the team manages to get the boat running and pushes off into the water, carrying the weight of their escape and the grief of losing a friend.

By the next morning, Baker knows they cannot simply sail away and ignore what is happening in the valley. He tells the team about the collider and insists that it has to be destroyed. Sofia steps in and explains that the machine is dangerously unstable, and if they try to blow it up, the resulting reaction would wipe out the entire world. The only real solution, she says, is to reach the Soviet base and shut it down by pulling a single power line directly from the source.

They set course for the Soviet base, and after hours on the river, they reach a barren stretch of land. Scattered across the ground are the bodies of soldiers who never made it out. Before they can process what happened, a wave of dinosaurs storms toward them. The team opens fire and struggles to hold their ground, but the chaos pushes Logan over the edge.

He unloads round after round in a panic, then breaks completely and turns the gun on himself. The dinosaurs swarm his body, and their frenzy gives the rest of the squad a narrow chance to slip away and continue their mission.

By evening, the team reaches the edge of the Soviet base. Baker contacts Jericho, reports their position, and demands that a helicopter be sent for extraction. After the call, they slip behind the outer wall and watch what is happening inside.

Borodin is addressing his remaining men, proudly calling the dinosaurs a weapon that can reshape the world and change the direction of the war. His speech falls flat, because none of his soldiers stand with him now. Even Con Nhen looks at him with nothing but hatred for unleashing these creatures on her homeland.

The Americans move in and slip through the base, quietly eliminating guards as they go. They spread explosives around the compound and cut open the cells holding several Russian soldiers who have already turned against Borodin. With some effort, they convince these men to stand with them instead.

Elsewhere in the compound, a small dinosaur wanders close to a group of Russian soldiers who react by shooting it. The moment the creature drops, a thunderous roar echoes across the base. The baby’s parents, who turn out to be full grown T Rexes, charge in after seeing their offspring on the ground. Overcome with rage, they tear through the facility and throw everything into chaos.

Amid the turmoil, Con Nhen spots Miller and instantly recognizes him as one of the Americans involved in the destruction of her village. She lunges at him without hesitation. Miller tries to defend himself while begging for her forgiveness.

Before either of them can break away, a dinosaur charges toward their position, forcing them to duck behind a vehicle. Even with danger closing in, Con Nhen keeps attacking him, unable to let go of her hatred. Miller apologizes once more, then pulls the detonator on an explosive he is carrying. The blast kills them both and sends the nearby dinosaurs scattering.

Sofia, Baker, and the others reach the laboratory just as the final phase of the experiment is underway. The collider is seconds away from opening another portal, and the only solution is to sever the cables and shut the machine down. Sofia steps forward to do it, but Borodin suddenly emerges from the shadows and tries to intervene.

Baker fires and wounds him, and Sofia unleashes her anger, spitting at him and shouting about her husband’s death. She then cuts the main cable, plunging the entire room into darkness.

A moment later, the emergency generator hums back to life and the lights flicker on. Borodin has vanished, and in his place a pack of dinosaurs is already pushing into the building, ready to attack.

They toss a smoke grenade to break the dinosaurs’ line of sight and open fire through the haze. In the confusion, Borodin makes one last attempt to reach the collider’s controls, desperate to bring the machine back online. He never gets the chance. A T Rex storms through the smoke, snatches him up, and ends his life in moments.

The hallways erupt into full chaos as more dinosaurs pour inside, blocking every obvious escape route. With the building falling apart around them, Sofia shouts that she knows another way out and leads the team through a side passage.

During the scramble, a dinosaur lunges out of the dark and grabs Eli. Baker reaches for him and tries to pull him free, but the creature is too strong. The others drag Baker away because staying any longer would doom them all.

They eventually reach a ladder. Baker orders the group to climb first while he stays behind to slow down the creatures closing in on them.

Outside, Colonel Jericho and his men arrive in their helicopters, and the moment they spot the dinosaurs, they open fire without hesitation. Inside the chaos, Baker breaks out of the facility and sprints across the grounds while tossing grenades to slow down the creatures behind him. One feathered dinosaur blocks his path, but Baker just lets out a quick laugh and drives his knife into its throat.

Right then, the charges planted throughout the base detonate. The blast engulfs the compound and the surrounding dinosaurs in a massive fireball. Baker is caught in the explosion and loses his life, while the rest of his team reaches the helicopter at the last possible second and lifts off as the valley burns below them.

Once they are in the air, Jericho shifts the blame onto the Vulture Squad, insisting that losing the collider ruined a chance for the United States to gain the upper hand in the Cold War. Sofia tells him there is no point arguing, because the collider is already gone and the dinosaurs have started moving out of the valley.

The movie ends with a quiet moment at an American military base, where a herd of peaceful plant eaters walks past the perimeter. It leaves a clear message that the danger is still out there.
