Written by Zhang and a team of young scriptwriters, the film revolves around a family-run bathhouse in Beijing. An aged father and his younger, mentally challenged son have been working hard every day to keep the bathhouse running for a motley group of regular customers. When his elder son, who left years ago to seek his fortune in the southern city of Shenzhen, abruptly returns one day, it once again puts under stress the long-broken father-son ties. Presented as a light-hearted comedy, "Shower" explores the value of family, friendship, and tradition.
