Eli Roth stars in this disaster-horror as a traveller caught up in the chaotic aftermath of a Chilean earthquake. While on a night out in an underground nightclub, American traveller Gringo (Roth) and his fellow partygoers find themselves fighting for their lives when a massive earthquake hits the town. They soon discover, however, that finding their way back to the surface is the least of their problems, when they emerge into the lawless streets and are forced to face a bloody fight for survival against marauding gangs of murderers, rapists and looters.
