Xu Zhe is known as the most outstanding healing writer. He is young, has a house, and does what he likes. He is a model of success. His words are known as chicken soup for the soul, soothing the hearts of countless readers. From his works, we can know that he is a kind, principled, wife-loving and family-loving man. However, his wealth is inherited from his father. One day, a new tenant came to the unit upstairs from Xu Zhe's house, which brought a huge impact to Xu Zhe's dull life; the new tenant Elaine is a beautiful and fashionable woman. One night, Elaine was suddenly found dead on the platform of the housing estate. The police took over the investigation, and Xu Zhe admitted that he was blackmailed by Elaine and pushed Elaine down the building by mistake in a rage. The case should have been closed, but the police psychologist Su Sir carefully observed Xu Zhe and believed that he was lying, and there were still many doubts about the whole thing. In order to find the truth, Su Sir pursued him relentlessly. Finally, it is discovered that Xu Zhe's wife Qi Qi knew that Xu Zhe and Elaine had an affair. This naturally makes Su Sir suspect that Qi Qi turned love into hatred and then killed people in revenge. Is this because Qi Qi is taking revenge on Xu Zhe's infidelity, or is there a case within a case, and a game within a game?
