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