Chen Xiaomeng (played by Xiao Yang) has always wanted to be an actor, but the cruel reality has left him struggling in the position of a supporting role. Chen Xiaomeng, who has no money, no job, no lover, no friends, and owes a large sum of money, thought of death, but even the god of death abandoned him, and his several suicide attempts ended in failure. One day, Chen Xiaomeng went to the bathhouse to take a bath and accidentally met a mysterious and wealthy man (played by Andy Lau). The man accidentally fell in the bathhouse and was sent to the hospital. Chen Xiaomeng, who picked up his storage room bracelet, decided to replace his identity and enjoy the life of a rich man. The impact on the head caused the man to lose his memory. With sporadic clues, he identified himself as Chen Xiaomeng, and followed the clues to Chen Xiaomeng's rental house, hoping that the familiar environment would help him recover his memory faster. In the process, the man met a self-media person named Li Xiang (played by Wan Qian), and sparks collided between the two.
