Motorpsycho or Motor Psycho is a 1965 film by Russ Meyer. Made just prior to Meyer's better-known Faster, Pussycat! Kill! Kill! (1965), the film explores similar themes of sex and violence, but focuses on a male motorcycle gang, unlike the female gang of go-go dancers featured in Faster, Pussycat!. Motorpsycho is also notable for containing one of the first portrayals of a disturbed Vietnam veteran character in film.
The story involves a veterinarian whose wife is raped by a motorcycle gang led by a sadistic Vietnam veteran. After the gang kills an old man, his wife teams up with the veterinarian to hunt down the gang.
