A regular family - Maria (Naomi Watts), Henry (Ewan McGregor) and their three children - traveling to Thailand for Christmas. They received an upgrade to a villa on the coast. After settling in and exchanged gifts, they go to the pool, like a lot of other tourists. A perfect holiday paradise until a distant noise becomes a roar. No time to get rid of the tsunami; Maria and the huge sweeping her way, Henry and other young people. Who will survive and what will happen to them?
