A teenager named Tammy finds her life turned upside down when her boyfriend, Michael, becomes the victim of a bizarre science experiment at the hands of an evil scientist. After a brutal attack by bullies, Michael is left unconscious and is clandestinely transported to a laboratory where his brain is removed. The mad scientist's nefarious plan is to transplant Michael's human brain into the skull of a robotic Tyrannosaurus rex. The procedure is a success, and Michael finds himself trapped within the mechanical body of a prehistoric beast, unable to communicate his true identity.

As the dinosaur with Michael's consciousness escapes from the lab, chaos ensues in the town. Meanwhile, Tammy and her best friend Byron begin to unravel the truth behind Michael's disappearance. They encounter the T-rex, and to their astonishment, Tammy senses Michael's presence within the creature. Realizing that her boyfriend's mind is trapped inside, she resolves to find a way to help him. The duo embark on a quest to rescue Michael's brain from its dinosaur prison and confront the scientist responsible for the outrageous experiment, facing challenges that test the limits of their courage and friendship.
