Cai Pu often calls Du Cai to keep him company when he is on night shift. One day, the two of them suddenly decided to see what images were recorded in the dashcam of Cai Pu's boss Huang Qiwen (Dai Liren), hoping that the boss, who has always been a playboy, could contribute some wonderful clips to relieve the loneliness of the two single men.
