A terrifying and emotional story based on one family's experience of the 2004 tsunami, THE IMPOSSBILE is a compelling account of perserverance and survival in the face of unimaginable disaster and chaos.

MARIA (Naomi Watts), HENRY (Ewan McGregor) 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.

Henry grabs the two youngest boys, SIMON and THOMAS, but it's too late: the wave smashes into him with incredible force and dislodges his grip. Maria is pushed underwater, where she is crushed and battered by debris to the brink of death. She finally surfaces in a raging black sea, which has completely submerged her three-story hotel and the surrounding landscape. Maria gasps for breath while she tries to understand what has just happened, convinced that her family has been obliterated in the blink of an eye. But then, her eldest son, LUCAS (Tom Holland), surfaces a few meters ahead in the wild flood. Face-to-face with something unexpected and incomprehensible, she must fight against all odds for her child's survival. And her own.
