In December 2004, close-knit family Maria, Henry and their three sons begin their winter vacation in Thailand. But the day after Christmas, the idyllic holiday turns into an incomprehensible nightmare when a terrifying roar rises from the depths of the sea, followed by a wall of black water that devours everything in its path. Though Maria and her family face their darkest hour, unexpected displays of kindness and courage ameliorate their terror.

Husband and wife doctors Paul and Kim Jordan need a drastic change. Distraught by the inexplicable death of their baby, Paul (C. Thomas Howell) convinces Kim to abandon their American lives and join a medical mission in Thailand. It seems to be just the distraction they need, until the day Paul is kidnapped by human traffickers who need a surgeon to operate on their wounded leader. Kim is left alone in a strange country, trying desperately to find her husband with no proof of what happened. While captive on the gangs' secluded island, Paul is caged with Malcolm Andrews (John Rhys-Davies), an Englishman being held for ransom. With nothing to do but talk, the two men quickly clash over philosophy, as Malcolm relies on a bold faith in God and Paul believes no god would allow these evils to happen in the world. Paul takes another hit when he finds his patient's condition much worse than he can handle on his own in such primitive conditions...
