The lovely assistant of an evil hypnotist has no idea that she is the descendant of a horrifying prehistoric sea monster she is mesmerized by her boss. When the monster comes forth, she goes on a killing spree. A promoter learns about the hypnotist's shenanigans and figures a way to cash in on the death and destruction. Meanwhile, each time the assistant is hypnotized and the monster emerges, she is able to better control it. The monster costume was created by master make-up artist Paul Blaisdell and is considered one of his best. ~ Sandra Brennan, All Movie Guide
