The story starts with a "white lie." Jian Bin, played by Geng Le ("In the Heat of the Sun") has been unemployed for three months but cannot bring himself to tell his wife of seven years (Xu Jing Lei -- "I Love You"). Their relationship has closed down, only able to talk about the most banal topics. Every morning he puts on a suit and tie, takes his briefcase and pretends to leave for work. But instead of going to work he spends the day riding the subway. In the subway, the camera discovers other couples and other worlds. Each pair has a different rhythm and a different way of communicating. Meanwhile, Jian Bin becomes desperate as he begins to run out of money and excuses. And we also learn that his wife has her secrets too . . . . Much of the action was shot in the new line of the Beijing subway. Director Zhang Yang (Spicy Love Soup, Shower, Quitting) plays a small role in this movie.
