Royal Tramp

The film is set in 17th-century China during the Qing dynasty. Wei Xiaobao is the brother of Wei Chunhua, a prostitute. By chance, he saves Chen Jinnan, the leader of the anti-Qing organisation Tiandihui, and becomes Chen's apprentice. The Tiandihui sends Wei as a spy to infiltrate the imperial palace to steal the Sutra of Forty-two Chapters.

In the palace, Wei pretends to be a eunuch, and meets the young Kangxi Emperor by coincidence, sparring with the emperor and becoming his trusted aide. He also makes enemies with the Empress Dowager. The emperor also introduces Wei to his bodyguard Duolong and orders them to help him get rid of Oboi, the overbearing regent. Duolong and Wei's attempt to assassinate Oboi fails, but Oboi gets defeated by the Empress Dowager eventually.

While confiscating Oboi's property on the emperor's order, Wei uses the chance to embezzle much of Oboi's wealth before returning to the brothel to free his sister. He is also sent by the Tiandihui to infiltrate the palace again and find an opportunity to assassinate the emperor and Oboi. The twins Shuang'er are instructed by the Tiandihui to accompany Wei on his mission, and they promise to marry him if he succeeds. The twins get into a love rivalry with the emperor's sister Princess Jianning, who also wants Wei to marry her.

By then, the Empress Dowager has discovered Wei's identity as a Tiandihui spy, while Wei has also learnt that she is an imposter. Wei is captured and imprisoned with Oboi, but Oboi's followers free Oboi and escape with Wei as their hostage. They encounter Chen and the Tiandihui members, and both sides clash. Oboi is ultimately killed by Chen, and everyone is surrounded by soldiers led by the Empress Dowager imposter. Just then, Jianning shows up with the real Empress Dowager and exposes the imposter, who fights her way out and swears vengeance on Wei.
