A Chilean vacation becomes a waking nightmare for a group of travelers when a devastating earthquake unexpectedly strikes while they're partying in an underground nightclub. Once outside, they find themselves locked in a battle for their lives against escaped convicts and other panic-stricken survivors who've already resorted to looting, rape, and murder. Eli Roth (who also co-wrote and co-produced), Lorenza Izzo, Ariel Levy, and Selena Gomez star in this terrifying shocker. 89 min.
