Once a Cop

Once a Cop is a 1993 Hong Kong action film, directed by Stanley Tong and starring Michelle Yeoh, Rongguang Yu, and Emil Chau. The film is a spin-off of the successful 1985 film Yes, Madam!, also starring Yeoh, and follows her character, Inspector Ng, as she goes undercover to take down a drug ring.

The film begins with Ng, now a successful inspector, receiving a commendation for her work in cracking down on a group of diamond smugglers. However, her success is short-lived when her childhood friend, Yung, is killed by a drug lord named Mr. Ko. Determined to avenge Yung's death, Ng decides to go undercover as a member of Ko's drug ring.

As she gains Ko's trust, Ng begins to unravel the extent of his operation, discovering that he is in fact part of a larger syndicate. Along the way, she meets a former police officer named Lam, who is also investigating the syndicate. The two team up to take down the organization and bring Ko to justice.
