A-Dan (played by Nick Cheung) and A-Jin (played by Peng Jingci) are good brothers who are as close as brothers. They go out into society together and have experienced many ups and downs together. A-Dan is timid and greedy for money, and often gets into trouble and asks A-Jin to help him clean up. In an accident, A-Dan angered the underworld boss Lei Qi (played by Anthony Wong), and then stole 200,000 public funds from the underworld boss Jackal Kun (played by Li Yaoming). Under attack from both sides, A-Dan and A-Jin had to embark on a journey of escape. The two down-and-out gangsters came to the beautiful Phuket Island in Thailand, where they met two pure and lovely girls and fell in love. What the bad guys didn't expect was that one of the two girls was Lei Qi's girlfriend and the other was a killer. Following the footsteps of the two, Lei Qi also came to the island.
