Knock Knock (18)

During a storm, married man Evan opens his front door to two rain-soaked girls called Bel and Genesis. He allows them in to use the telephone and dries their clothes. The girls subsequently seduce Evan and the next morning, with the girls leave, Evan is crippled with guilt. The following night, Bel and Genesis return to the house and knock Evan unconscious so he must become an unwitting pawn in their sick and twisted game of torture and atonement.
