The sequel to the Spanish smash hit that Sony Home Entertainment will release here in the States next year. For people familiar with the first film, the clip picks up just about 15 minutes after authorities lost contact with the people locked in the building under quarantine. Nobody knows what happens inside. Outside is chaos…a SWAT unit enters the interior of the house to monitor the situation and determine what is happening. Below is the Spanish screener directed by Jaume Balaqueroy and written by Paco Plaza. The film stars Manuela Velasco, Jonathan Mellor, Oscar Sanchez Zafra, Ariel Casas and Alejandro Casaseca.
