Tom Holland in the dramatic movie The Impossible.

The Impossible Movie Synopsis: Maria, Henry and their three sons begin their winter vacation in Thailand, looking forward to a few days in tropical paradise. But on the morning of December 26th, as the family relaxes around the pool after their Christmas festivities the night before, a terrifying roar rises up from the center of the earth. As Maria freezes in fear, a huge wall of black water races across the hotel grounds toward her.

Based on a true story, The Impossible is the unforgettable account of a family caught, with tens of thousands of strangers, in the mayhem of one of the worst natural catastrophes of our time. But the true-life terror is tempered by the unexpected displays of compassion, courage and simple kindness that Maria and her family encounter during the darkest hours of their lives.
