Qi (Simon Yam) is a professional pickpocket. Before he went out that day, a finch flew into his house. It refused to leave even if he released it, and stayed in the dark house. During lunch, Qi asked his friends about the symbolic meaning of the finch, and his friends said it was a precursor to getting into trouble. Of course, this was a joke. Qi led his four brothers to steal on the streets of Hong Kong to make a living. The four of them rode a bicycle together, crooked and twisted, with a special brotherly interest. Qi likes to take pictures of street style in his spare time. On this day, a woman Zhen Zhenni (Kelly Lin) who ran by in a hurry attracted his attention, and he quickly took a picture of her. Coincidentally, his other three brothers were entangled by the same charming woman one after another. This woman always walked in a hurry, but the four brothers were fascinated by it. Until they were severely taught a lesson. Only then did they realize that Jenny was the mistress of the wealthy businessman Mr. Fu (Lu Haipeng), and she wanted to get her passport back from Mr. Fu and live a free life. The four brothers decided to take a risk for her. For no reason. However, Mr. Fu is also a veteran in the world, and a contest is about to begin.
