We follow Chan Wing-yan (Tony Leung) before his death. This storyline explores his growing bond with his psychiatrist, Dr. Lee (Kelly Chen), and his dangerous game with a mysterious mainland gun-runner, Shen Cheng (Chen Daoming). The Present (Post-2002):
Directed by Andrew Lau and Alan Mak, Infernal Affairs III is a bold experiment in non-linear storytelling. It demands total focus from its audience, trading the visceral tension of the first film for a haunting, psychological exploration of guilt, identity, and the desperate search for redemption. A Dual Narrative: Before and After
Taking place months before the events of the first film, this timeline explores the final days of Yan (Tony Leung Chiu-wai) as an undercover mole inside Hon Sam’s (Eric Tsang) triad syndicate. We witness Yan’s escalating psychological exhaustion, his burgeoning relationship with his therapist Dr. Lee (Kelly Chen), and his fateful encounters with a mysterious Mainland businessman named Shen Cheng (Chen Daoming). Infernal Affairs III
As the 2003 timeline progresses, the narrative dissolves into a subjective psychological thriller. Lau begins to suffer from severe dissociative identity disorder, fueled by guilt and post-traumatic stress. He projects his own identity onto Superintendent Wing, convinced that by exposing Wing, he will finally "catch the bad guy" and validate his own status as a righteous cop. In a tragic and brilliant narrative twist, Lau begins to hallucinate, internalizing the identity of the man he killed: Chan Wing-yan. He literally becomes his own worst enemy, hunting himself down in a desperate bid to cleanse his soul. Star-Studded Brilliance and Key Performances

The lines between who is telling the truth and who is lying are further blurred, making it difficult for both the characters and the audience to distinguish reality.
