A film starring Mai Jia, Andy Lau and Ceng Zhiwei, seeking the heroine.

should be the best lucky star. The heroine is Zhang Aijia. A transnational case stumped the Hong Kong police. At a high-level secret meeting, Inspector Cao (Cao Defa) accepted the advice of his subordinates and decided to send non-police officers to steal valuable diamonds from Japanese gangsters. As usual, he found the old partner of Wuxing, but in the end, only Swertia japonica (Sammo Hung) agreed to take over. After some screening, they found five out-of-tune police officers from inside the police station, namely Wang Lun the dog (Alan Tam), Fat Leopard (Zheng Zeshi), Lan Bao (Andy Lau), Band Friends (Chen You) and Li Health Care (Billy Lau). The funny and off-line skills of this new group of five lucky stars are better than those of the old ones, making more jokes.
