Continuing from where the first film left off, the pirates vow that they must kill Dragon Ma for revenge. On recommendation of the Chief of Marine Force, Dragon Ma is transferred to be in charge of the district of Sai Wan after the Superintendent, Chun, is thought to be staging his arrests. Though Chun has an excellent record, the "criminals" he has been engaging are shot and killed, so there is no evidence against him.

Dragon Ma and his subordinates meet Yesan and her cousin, Carina, at a teahouse. He learns that Carina is a member of the Chinese revolutionaries headed by Dr Sun Yat-sen. Dragon identifies himself as the new superintendent of Sai Wan Police Station, after realizing that all of his policemen except one has been taking bribes. Ho, the only upright policeman around, tells them that a gangster named Tiger Ow with gambling dens and other illegal businesses is the kingpin of the town.

As his men at the police station are too cowardly, Dragon is forced to confront Tiger with only Ho and the three friends he brought with him from the Marine Police. Following a big fight where the policemen are badly outnumbered, the Marine Police show up with guns and force the gangsters to surrender. After one last fight with Ow, all the gangsters are sent to prison, inspiring the police at the station to do a better job.

Dragon is put in charge of the Governor's security for a birthday ball he is throwing for his adopted daughter. Chun collaborates with a group of revolutionaries to implicate Dragon in a theft of the Governor's diamond pendant, and Dragon is arrested. After the ball, Carina is kidnapped by agents of the Empress Dowager, who are working with Chun; they trap her in a wardrobe at Yesan's house. Yesan, Li, Ma, and Ho arrive. Li hides but ends up threatened by one of the imperial agents. Ma and Ho, who are handcuffed together, enter the bathroom. While they are in the bathroom, the commissioner arrives.

As Yesan hangs up his uniform, Ma and Ho see the keys to the handcuffs. They break free and hide under the bed, losing the key to the handcuffs. They see the Imperial Agents with Carina in the wardrobe. Yesan and the commissioner sit down to talk. The Commissioner demonstrates how to handcuff two people by handcuffing himself to the armchair but can not break free. Chun arrives to visit Yesan, and the commissioner hides under the bed, where he sees Ma and Ho. Yesan finally gets Chun to get out of her house, when Ma, Ho, Tung and Yesan defeat the Imperial agents. Eventually the Imperial Agents are arrested, the revolutionary chief escapes, and Dragon is handcuffed by Chun so that he can be brought to the main prison. Carina flees town with the help of the revolutionaries. Chun arranges for Dragon to be killed by a prison warden.

The pirates attack both Dragon and Chun with axes, but they are eventually driven off after the police show up. Dragon is handed over to the prison warden, tied up in a sack, and thrown into the sea. The revolutionaries save Dragon and take him back to their hideout above a medicine store, where they try to enlist him. Dragon refuses to actively help them, saying that he is just a Hong Kong cop. The head of the pirates falls sick and the pirates enter the medicine store to ask for some herbs. Dragon intervenes and offers to pay for their medicine, causing the pirates to think much better of him.

The Imperial agents arrive and apprehend most of the revolutionaries, to gain possession of the black book. Dragon helps Yessan and Miss Pak escape while safeguarding the book. After a frantic run and fight, he defeats them with the help of the pirates. The Police Commissioner arrives with a huge police cohort and orders the arrest of Superintendent Chun, now fully aware Chun is trying to murder Dragon. Chun tries to run, but a large bamboo-and-wood stage facade falls on Chun while he attempts to retrieve his moneybag. Dragon, on order of the Commissioner, takes charge of the police.
