The story is a miniature society with views on love and life values. Let the characters exclaim that "When it comes to love, any age is foolish." Hidden deep in the love story and family values is the ideological struggle and the lessons of the times.

Inspired by Chuyện Người Con Gái Nam Xương and Đèn Âm Hồn, the story is set in a rural village in Northern Vietnam during the feudal era. Thương, a mother raising her son Lĩnh alone while awaiting her husband's return from war, faces eerie events after Lĩnh accidentally discovers a mysterious lantern. The boy begins calling the shadow cast on the wall his father. According to the village shaman, the lantern is a đèn âm hồn, capable of summoning vengeful spirits. Strange and haunting occurrences unfold, leaving Thương and the villagers to question: is the shadow truly Lĩnh's father or something far more sinister?
