For the past five years, Lin has been looking after the son, Yo-yu, and the elderly mother, Mrs. Chou, of his deceased boyfriend, Li-wei. They live together as a family because Lin simply can't let go of Li-wei. So he does it by living the life Li-wei had and loving the people Li-wei loved. But after Mrs. Chou passed away, her other son Li-gang returns from overseas and discovers that Mrs. Chou's property has been passed down to Yo-yu, whom Lin has legally adopted. Li-gang contacts the police, accusing Lin of killing his mother for attempting to take over the property. As the ensuing investigation continues, more and more evidence mounts against Lin.
