Three days before the return of Macau, five assassins with deep feelings for each other. The assassin Ah He (played by Nick Cheung) and his wife Ah Jing (played by Josie Ho) returned to their hometown with their one-month-old child. Ah Huo (played by Anthony Wong) and Ah Bo (played by Lam Suet) were ordered by the underworld boss Da Fei (played by Simon Yam) to hunt down Ah He, but another pair of good brothers Ah Tai (played by Francis Ng) and Ah Mao (played by Cheung Yao Yang) heard the news and came to stop them for the sake of friendship. The conflict suddenly broke out in Ah He's house, and then quickly returned to calm. In the end, they decided to do a big deal together to rescue Ah He. At Xie Fu (played by Cheung Siu Fai), they were presented with two choices: assassinate Egg Roll Qiang (played by Lam Ka Tung) or rob a ton of gold... In the end, they chose the former, but they unexpectedly met their mortal enemy Da Fei in the restaurant, and a fierce battle was inevitable.
