Two of Hong Kong cinema’s most iconic leading men, Tony Leung Chiu-wai and Andy Lau Tak-wah, face off in the breathtaking thriller that revitalized the city-state’s twenty-first-century film industry, launched a blockbuster franchise, and inspired Martin Scorsese’s The Departed. Chan Wing Yan, a young police officer, has been sent undercover as a mole in the local mafia. Lau Kin Ming, a young mafia member, infiltrates the police force. Years later, their older counterparts, Chen Wing Yan and Inspector Lau Kin Ming, respectively, race against time to expose the mole within their midst. Set during the uncertainty of the city-state’s handover from Britain to China and steeped in Buddhist philosophy, these ingeniously crafted tales of self-deception and betrayal mirror Hong Kong’s own fractured identity and the psychic schisms of life in a postcolonial purgatory.
