After years of illness, Ken's wife finally passes away. Ken returns to his job as streetlight repairman after the funeral. Having to work at night, he rarely sees his daughter Ann, who develops a fear for darkness since her mother dies. Often left alone at home, she learns to grow up at a tender age. She makes her father agree to go out and play with her on the night of Mid-Autumn Festival, but Ken breaks the promise because of work. During the festive season, father and daughter try hard to re-capture moments of love and concern for each other.
