University professor Deng Huan and his girlfriend Yan Zi boarded the "Dream Star" luxury cruise ship for vacation. It was originally a pleasant trip, but bizarre murders occurred one after another. The heirs of the fifth family died tragically one after another, the methods of the secret room were strange and difficult to solve, and the grudges of wealthy families on the cruise ship were intertwined with old cases that had been settled for thirty years. Deng Huan teamed up with the police and friends to solve mysteries, uncovering the family's dark past of smuggling and arson for revenge, and solved a series of murders in a storm at sea, so that the injustice could be vindicated and the crime finally punished.
