Diane Harper, Jane Longenecker, is the county dog catcher who teams up with her ex-welding artist partner, Tom Banning, Matt Borlenghi, and his 12-year-old brother Michael Banning, Jake Thomas, as they search for their three‑legged dog, Lucky, in a small town shadowed by strange, dangerous happenings. The trio’s ordinary day-to-day routine quickly spirals into a fight for survival as fear grows and the forest around them becomes a deadly playground for a new predator. The family bond and neighborly routines are tested as the mystery deepens and a creature stalks the woods, turning every outing into a potential trap.
Paula Kennedy, Joanna Pacula, runs Paula Kennedy’s Genetic Research Co. (Gereco) and experiments with the DNA of a long-extinct, carnivorous dinosaur, pairing it with a modern crocodile to produce two hybrids inside the Gereco lab. The ambition behind the project is shadowed by secrecy, and Kennedy withholds critical facts from Sheriff Harper, telling him only that a dead creature killed Campbell’s assistant. The lab’s risky venture sets off a chain of brutal events that cut through the town’s tranquil veneer and put ordinary people in the crosshairs of a rampaging predator.
Dr. Campbell, Bruce Weitz, is among those drawn into the escalating danger when the hybrids begin to behave unpredictably, leaving a trail of violence in their wake. The first violent incident claims Campbell’s assistant, then another victim follows before the creatures manage to escape from the lab’s bounds. The discovery of the truth behind the creatures’ genesis is buried beneath a tangled web of corporate secrecy, fear, and the authorities’ desire to keep the public calm.
As the threat moves from the lab to the lakeside town, Diane and Tom’s search for Lucky intensifies. They navigate dense woods and increasingly perilous terrain while trying to protect Michael’s memory and their own fragile futures. The revelation that the Dinocroc, the more menacing hybrid, has begun to stalk the area ramps up the tension: it kills two hunters in the woods and leaves behind signs of its relentless hunger. The creature’s presence turns even familiar places like the woods and the dock into potential deathtraps, and the family’s quest to reunite with their pet dog becomes a race against time to save themselves.
To confront the rising threat, Kennedy enlists an Australian crocodile hunter, Dick Sydney, Costas Mandylor, whose experience with dangerous beasts adds a grim professional edge to the town’s improvised plan. They soon realize the Dinocroc’s aggression is not a temporary incident but a full-blown menace that will not be contained by ordinary means. The community’s resolve is put to the test as more people vanish or are found fatally wounded in the wild, and Sheriff Harper rallies his deputies to mount an effective counterstrike, even as fear drives some to overstep boundaries in a desperate bid for safety.
The next chapter of the crisis unfolds with the heartbreaking discovery of Michael’s damaged bicycle and his remains hidden in a ruined shed, a grim reminder that the danger is personal and intimate. Tom, who learns of his brother’s fate, rides home in a haze of grief, the loss crystallizing his determination to protect those who remain. He shares a quiet, impassioned moment with Dick Sydney, who reveals a personal history with crocodiles and the reasons behind his relentless pursuit of the killer, adding a somber layer to the battle between humans and predators. Diane returns to comfort Tom, and together with Lucky, they cling to what little hope they have left.
The Dinocroc’s brutality grows even as law enforcement struggles to keep pace. Five deputies are killed in brutal fashion while searching for the creature, their deaths underscoring the real stakes of the confrontation. With the body count rising, the plan shifts toward a dramatic trap in a tunnel, where gas is used in an attempt to neutralize the monster once and for all. Harper dispatches dogs as bait, a decision that Diane and Tom strongly oppose, and they confront the sheriff, challenging him to abandon the more brutal methods in favor of a safer, more measured approach. The escape that follows tests their courage and resourcefulness, as they work to free the police dogs and execute a desperate gambit to end the threat.
Even as the town seems to believe the danger has been contained, the Dinocroc reawakens in the tunnel, disrupting an on-site news crew and turning the event into a sensational spectacle for reporters. Kennedy arrives, filmed and grilled by the media, and the truth behind Gereco’s experiments remains out of reach as the creature closes in on Tom and Diane. The couple finds shelter beneath a truck, their nerves steadied only by the distant rumble of a passing train that could become their last line of defense. They lure the Dinocroc onto the tracks, a plan that hinges on timing and luck, while a train roars through and finally rams the beast, halting its rampage.
In the aftermath, Tom exacts a final act of vengeance, driving a makeshift stake into the creature’s brain through its eye with a small pipe, a grim echo of the losses he has endured. As dawn breaks, Tom and Diane drive away together, contemplating a hopeful escape from the nightmare they’ve endured and a chance at rebuilding their lives. The camera lingers on the last scene, showing the Dinocroc moving slowly across the road, a quiet, unresolved reminder that danger can linger long after the immediate panic has passed. The town’s shoreline and wooded outskirts hold the memory of what happened, a stark contrast to the calm that waits beyond the horizon.
