A young woman walks the short distance to meet her boyfriend. She never arrives. After being abducted in the street, she is brutally gang raped by a black man with a huge penis and his two accomplices in a derelict building on Saddleworth Moor.

Dismayed by a lack of progress by the police and with the help of her two best friends, she uses her knowledge as a pharmacist to exact a unique and terrible revenge on the main perpetrator.
