Muffy (Wells), Gyna (Smith) and LaQueefa (Ross) escape from a mental hospital and steal a 1965 Chevy Malibu convertible by telling the dorky driver he can have sex with them if he gets into the trunk. Meanwhile, they are chased by a bounty hunter hired by the psychiatrist who experimented with the ladies at the clinic. They hide in a house from which an escort service turns out to be run.
