As animal rights activists ransack a laboratory, they get more than they bargained for when one of the caged "animals" unleashes a ferocious appetite. Leaving grotesquely mutilated dead bodies in its wake, the scientific engineered beast - with the body of a lion, claws of an eagle, fangs of a viper, skin of a rhinoceros and tail of a serpent - attacks Charlie. With Charlie's life on the line, Walter must come face-to-face with both his past and the beast.
