<p>　　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.<br/>　　Taking a few cues from H.P. Lovecraft’s “The Dreams in the Witch House,” &quot;Venus&quot; piles on the blood and bombshells like a double bill of &quot;Demons 2&quot; and &quot;The Sentinel&quot;.</p>
