Ding Bo (Chen Po Lin) and his friends Nan Feng (Fan Bingbing) and Fei Zao aka Fatso (Fei Long) are a trio of 20-something outsiders who have no intention of sitting exams and getting into universities. When they need a new home, they answer an ad placed by lonely, retired Chinese opera singer Chang Yue Qin (Sylvia Chang), who is mourning the death of her son, and move into her sprawling Chengdu apartment. Right off the bat, the four clash over lifestyle and values, with the bratty trio seeing fit to steal from her and invade her privacy. However, slowly but surely a bond among them develops and everyone eventually learns something from the next.
