Evil Spawn

A scientist is locked in the laboratory by his assistant Evelyn Avery and a mutating creature attacks him. He turns into a monster and then he attacks a young man outside the building, but is killed by his girlfriend that crashes her car on him. Meanwhile, the aging actress Lynn Roman, who is a former famous star, is fighting for a lead role in a movie directed by Mark Randall. However, Mark wants a younger actress between twenty and twenty-five years old for the role. Out of the blue, Evelyn meets Lynn and tells that her secretary Elaine allowed her to meet Lynn to show an injection with a serum developed by Dr. Emil Zeitman that would make her younger again. Lynn uses the experiment and turns into a monster, becoming a threat to her friends.
