Ah Cao (played by Chapman To) is a "bounty hunter", that is, a person who lives by taking bounties. This time, Ah Cao needs to catch the robber Li Jianhui (played by Wang Ziyi) to get the 400,000 yuan bounty from the police. According to the intelligence, he came to a mysterious hotel, and the news said that this was the last place where Li Jianhui appeared. The owner of the hotel (played by Alex Man) is a weird person. He is suspicious on weekdays and posted a bounty to find his daughter. The bounty is over 100 million. What's even weirder is that the waiter Sun Langqing (played by Fiona Sit) in the store has repeatedly claimed that she is the daughter of Boss Sun, but Boss Sun denied it. Not only are there strange bosses and clerks, but the guests in the hotel are also suspicious. The hunchbacked and buck-toothed Coconut Man (played by Wang Ziyi) moves in secret all day long. It is said that people often commit suicide in the hotel... Can Ah Cao successfully get the bounty? Can the secrets in the hotel be revealed?
