Sam (Gerard Butler) used to be an idle drug dealer. After his wife Lin (Michelle Monaghan) converted to God, she refused to be a well-paid stripper and found an ordinary job, which made Sam feel irritated. However, every time he was forced to accompany his wife to church, his attitude seemed to change gradually. Until one day, he suddenly told his family that he would follow a missionary to Sudan. The family was stunned but had no choice but to let him go, but this trip completely changed Sam's life trajectory. In the night of Sudan, Sam was always awakened by the noise, and the old and young in the village rushed in the opposite direction. At this time, he learned that this was because his parents wanted to send their children to a safe place to sleep, because maybe the village would no longer exist tomorrow. Sam, whose heart was greatly shaken, decided to build an orphanage here. However, in the turbulent environment and the enemy's ruthless killing, protecting the orphanage was far more difficult than building it. Sam's journey had just begun... This film was adapted from the true story of a man named Sam Childers.
