When go-go dancer Lucía nicks a fortune in designer drugs from her mafia employers, the mobsters’ dogged pursuit forces her to seek sanctuary with her estranged sister Rocío and niece Alba in “The Venus,” a decrepit apartment complex on the outskirts of Madrid. As terrible, rotten, no-good luck would have it, Lucía soon finds herself sole guardian to little Alba after Rocío suddenly flies the concrete coop, unable to handle the supernatural stress of living in a monolith that is apparently also host to a malignant evil — one that invades its tenants’ waking nightmares.　　Taking a few cues from H.P. Lovecraft’s “The Dreams in the Witch House,” "Venus" piles on the blood and bombshells like a double bill of "Demons 2" and "The Sentinel".
