Starring Mischa Barton (‘The Sixth Sense’), Jackson Davis (‘Lonelygirl15’), Cayleb Long, Tracie Thoms (‘Death Proof’), Bailey Anne Borders (‘The Fifth Wave’) and Sarah Nicklin, the plot of ‘The Basement,‘ which Sam Santiago of likens to a cross between ‘Silence of the Lambs’ and ‘Split,’ is about a L.A. serial killer known as The Gemini (Davis), who tortures and ultimately murders his victims in the dungeon-like basement of his San Fernando Valley home. By the time the movie opens, Gemini has already claimed seven victims, all of whom he has horrifyingly maimed and decapitated with a blowtorch, but Craig Owen (Long), the famed musician who Gemini has chosen for his eighth victim, and Craig’s beautiful wife Kelly (Barton) prove every bit the killer’s equal in the art of psychological warfare, giving rise to one of the more diabolical plot twists in recent memory.
