The fat Ah Xiang (played by Zheng Zeshi) is the owner of a gas shop. He is kind, optimistic and generous. He has a beautiful wife and a lovely daughter, and lives a happy life. One day, he returned home halfway, but found that his wife was committing adultery. Although Ah Xiang was very angry, he suffered the consequences because of his personality. Ah Xiang went to a bar to drown his sorrows in alcohol and complained to the dancer Fanny (played by Guan Yonghe). As a result, he hired a killer from the Vietnamese gang through her to kill the adulterer. The next day, Ah Xiang woke up and went home, but he had long forgotten about hiring a killer, so he watched his wife and the adulterer being hacked to death. Ah Xiang's nightmare has not ended yet. He is also facing a high reward from the Vietnamese gang. In desperation, Ah Xiang fled to Guangzhou, where he met the ruthless Wu Shu (played by Simon Yam). Wu Shu promised to lead his men to help Ah Xiang solve the problem of the Vietnamese gang, but this move made Ah Xiang's life fall into ruin...
