Young girls are disappearing around the Mary Magdalen Halfway House for Troubled Girls. Desperate to find her sister, Larissa Morgan (Janet Tracy Keijser) goes undercover to investigate the Catholic-run institution. Once inside, she meets a nasty nun, a peculiar priest, a homicidal handyman, and lots of bad girls with attitude. Larissa endures catfights, corporal punishment, and long, hot showers before she learns the ultimate secret of the Halfway House - a huge, one-eyed monster with tentacles and a taste for female flesh!
