Ask for the name of a movie, in which there is a man named Lucas. Their family went on a trip and met with a flood, but their mother and son survived.

Maria and Henry took their three sons to spend Christmas in Thailand. Unexpectedly, on the day after Christmas, while the happy family was enjoying their leisure time by the pool, a huge wave of ten thousand feet like a beast came head on. Maria, who was shocked by the scene before her, was unable to respond at the moment and was unfortunately hit by huge waves; Although Henry caught his two sons in time to escape, it was still too late, and the fierce flood finally dispersed them. Maria, who was once stunned by the huge waves, woke up to find herself floating on the sea, and all the scenery around her had been submerged under the water. She was convinced that all her family had died, but she found her eldest son Lucas floating on the sea just a few meters away from her. Maria suddenly seemed to be given a shot in the arm, and she decided to try her best to leave alive with her eldest son Lucas.
