Gaia, a new religious movement who advocates that the Doomsday is near, wildly makes disciples, and its founder FONG SAI-KWAN is called by his disciples as "Heavenly Brother". Professor CHU HOK-LAI, who studies Deism, once committed arson, and he was transferred to Bok On Hospital for treatments after serving his sentence in a psychiatric hospital. LAP-YAN and CHI-SUM see some disciples of Gaia staging a protest and to their surprise, they spot SHUM SUK-YEE, the high school campus belle, who is also participating in the protest. As the two go to a night club, looking for SUK-YEE's husband, LAP-YAN is entangled by LAM CHUNG-YAN, a night club escort girl. On the other hand, CHUNG-YAN's best friend YUI-CHI introduces a hoodlum - LO BO to her, letting her to distribute drugs. When the patients are taken out by the hospital, HOK-LAI takes the opportunity to run away, and nowhere to be found. LAP-YAN gets headhunted by WING-HENG, becoming a consultant of the Bok On Hospital. With YUI-CHI persuading CHUNG-YAN to stop drug trafficking, the two have a quarrel in the restroom. Shortly afterwards, YUI-CHI is found dead in the ladies' room.
