Lawrence Ah Mon directed Dealer/Healer, a 2017 Hong Kong-Chinese action crime drama film starring Sean Lau, Gordon Lam, and Jiang Yiyan, with guest appearances by Louis Koo and Zhang Jin. The film is based on Peter Chan's recovery from heroin addiction as a former member of the Hong Kong triad. Chan, who is played by Lau in the film, was also one of the film's producers. Dealer/Healer was released on the 12th of May in China and the 18th of May in Hong Kong.
Chan Wah (Sean Lau), La Ba (Gordon Lam), Kitty (Zhang Jin), and their brothers lived in Hong Kong during the 1960s and 1970s, when the police were corrupt and triads ran the city. Chan was recognized as the head of the "Thirteen Naughty Children of Tsz Wan Shan," despite his arrogance. Chan later meets his true love, Ho-yau (Jiang Yiyan), and spends the rest of his life with her. However, Chan's good times were short-lived while he was being pursued for narcotics trafficking. Fortunately, Chan was able to avoid death with the help of his friend, Halley (Louis Koo), the head of the police force's Anti-Drug Unit, but he was unable to escape the law. Chan's father died after he was released from prison, and Ho-yau went missing, leading him to blame himself heavily. Chan has come to terms with his previous sins and is ready to start a fresh page in his life. He was named one of Hong Kong's Ten Outstanding Young Persons for his active participation in helping teenagers recover from drug addiction. He also steered La Ba and Kitty in the correct direction and assisted in resolving triad issues, earning him respect from both the triads and the police. Chan runs across Ho-yau while attending a drug treatment seminar in Japan and wishes to be with her once more.
