Inspired by actual events, Days of Darkness director\co-screenwriter Jake Kennedy's sophomore shocker tells the story of single mother Amelia (Marieh Delfino), who turns to stripping as a means of making ends meet and winds up the unwilling subject of a grim purification ritual. When sexy dancer Suzy takes a beating that leaves her unable to perform, she asks Amelia to cover her latest gig. Reluctantly accepting so her friend can convalesce, Amelia begins to grow uneasy when her driver (Tony Todd) taxis her to a dark and remote location. Once inside, Amelia finds herself imprisoned with a number of other unchaste women by a sadistic captor (Graham McTavish) who uses various torture methods to rid them of their impurities. Produced and co-written by Automaton Transfusion director William Clevinger, Penance also features Henry: Portrait of a Serial Killer star Michael Rooker.
