While boating in a boat we never see and possibly water-skiing without getting wet, a quartet of teens, Reg (Don Sullivan), Skip (Paul Pepper), Julie (Mitzie Albertson), and Pam (Brianne Murphy), accidentally discover an island run by a mad scientist named Doctor Myra who intends to turn everyone in the United States into a communist zombie, but we really don’t see any zombies and only a couple commies. Luckily it’s “Dreamboat” Don Sullivan to the rescue. I don’t seem to remember Don Sullivan singing in this one, but you should take appropriate precautions.
