Plot:Rampage delves into the subject of legal insanity, so often the default defense in modern-time gruesome crime trials. Alex McArthur plays an outwardly normal guy who goes on incredible killing and mutilating sprees until (and even after, when he escapes for a short time) he's captured. When he comes to trial, the liberal DA (Michael Biehn) is torn between his own leftist leanings and the reality of the heinous crimes for which the accused is being tried. He must argue for the death penalty.

Plot:Primatologist Davis Okoye shares an unshakable bond with George, the extraordinarily intelligent, silverback gorilla who has been in his care since birth. But a rogue genetic experiment gone awry mutates this gentle ape into a raging creature of enormous size. To make matters worse, it’s soon discovered there are other similarly altered animals. As these newly created alpha predators tear across North America, destroying everything in their path, Okoye teams with a discredited genetic engineer to secure an antidote, fighting his way through an ever-changing battlefield, not only to halt a global catastrophe but to save the fearsome creature that was once his friend.
