THE STOOL PIGEON examines the fine line between cops and their undercover informants. Police Detective Don Lee (Nick Leung) makes a bad call, causing a close informant to be injured. A year later, he must locate a new man to go undercover inside a jewel-theft ring. Ghost, Jr. (Nicholas Tse) doesn't want to do it, but Lee can offer deals and apply pressure that makes it hard to say no. Lee makes decisions based on the progress of his case, but not always to the benefit of his informant. Ghost must play a role but can't decline the chance to do what's right.
