Dr. Neil Hamilton (Paul Coufos) receives a call from his mentor Dr. Kate Travis (Jackie Burroughs) about a young boy named Bobby, whose deficient growth has been treated with Travis' experimental serum. Bobby has swiftly and unexpectedly grown larger than a full-grown adult and become violent. To find an antidote, Neil takes a sample of the serum back to his lab at a university science complex. There, animal-rights activists led by Mark Hales (Réal Andrews) and Neil's girlfriend Alex Reed (Lisa Schrage) are protesting the work of Prof. Edmund Delhurst (Colin Fox (actor)), who claims to oncology cancer but in fact subjects animals to experimentation seeking a cure for baldness.
