Scientists working at a top-secret government research facility are conducting experiments to resurrect a dinosaur using prehistoric DNA. The scientists believe the experiment will lead to fame and fortune but instead it leads to death and destruction when the terrifying T-ReX grows at an accelerated pace. After rampaging through the research centre the fearsome creature escapes into nearby Devil's Creek where a family are enjoying a summer vacation. As the government hires a squad of deadly mercenaries to lead a search and destroy mission, the family realise that terror is not extinct as they face the deadly wrath of the Primeval Predator. It's man against the most vicious beast of all time - and neither will survive while the other is alive.
