Fifteen years after the original film, the philosophical Lieutenant William F. Kinderman is investigating a baffling series of murders on Georgetown that all contain the hallmarks of The Gemini, a deceased serial killer. His investigation eventually leads him to a catatonic patient in a psychiatric hospital who has recently started to speak, claiming he is The Gemini and detailing the murders, but bears a striking resemblance to Father Damien Karras.

This is the tale of a crazed family of weirdos led by Crawldaddy who like to kill people and remove their skin.

When an upwardly mobile couple find themselves unemployed and in debt, they turn to armed robbery in desperation.
