A freak hurricane hits Los Angeles, causing man-eating sharks to be scooped up in tornadoes and flooding the city with shark-infested seawater. Surfer and bar-owner Fin sets out with his friends Baz and Nova to rescue his estranged wife April and teenage daughter Claudia.

After stealing a huge stash of drugs, speed freaks Hector and Dorena plan to cook up an enormous batch of crystal meth and get rich quick. Hector's old buddy Merle has the perfect hideout/meth lab: an old, abandoned farmhouse in the woods where no one will ever find them. Unfortunately, no one will hear their screams either. Turns out, they may not be alone after all. It seems this farmhouse is the site of a horrific urban legend. Now, holed up together with nothing to do but snort, smoke and shoot up, the strung-out "cookers" fall prey to paranoia, private demons and terrifying visions which, whether they are hallucinations or hauntings, are equally terrifying and just as deadly!
