The typhoon passed, and the gloomy sky was unknown how long it would last over the closed island. In the old houses, several gang members were suddenly attacked. The man was agile and cut off the head of the leader Ma Tiantai and disappeared into the night... The next day, the island policewoman Xiaohe (Celina Jade) fell from a tree to save her cat. A passerby rescued her. He called himself Abu (Wu Jing). The two met three Thai gangsters at a food stall. Xiaohe was upright but could not resist. Abu took action to knock down the three and stayed in the police station with Xiaohe. Abu made the police officer Taishan (Sammy) who was interested in Xiaohe very upset. His colleagues Guan Gong (Hui Shaoxiong) and Liang Bao (Alex Fong) teased with cold words, adding a lot of warmth and vitality to this lonely island police station. Ma Tiantai's widow, Sasaki (played by Aoyama Junko), ordered his subordinate Fei Rong (played by Lin Xue) to lead people to the island to retrieve Ma Ye's head to complete the body. Unexpectedly, Xiaohe and Taishan found the body hiding place during patrol and took the body away. Fei Rong and others rushed into the police station to grab the body. In the melee, Liang Bao was shot and killed. The port was reopened, and a large number of police officers landed on the island. Abu was detained for a short time on suspicion of beheading and then released. Although he could hide from the police, he could not get rid of Sasaki's pursuit. After Xiaohe was kidnapped by the other party, Abu had no other choice...
