Master Z: The IP Man Legacy

After being defeated by Ip Man, Cheung Tin Chi lives a depressed life and stays low profile, moonlighting as a mercenary briefly, before choosing to leave behind the world of martial arts. One day he runs into the opium addict Nana, who is in debt to Tso Sai Kit, and her friend Julia, who are fleeing from Kit. He ends up fighting with Kit's gang and defeats the whole gang alone. The police arrive and arrest everyone. Kit and his gang are released due to the police commissioner being corrupt, while Nana and Julia are released by name-dropping Julia's brother, Fu, the owner of Gold Bar operating on Bar Street. Tin Chi is eventually released too. Following the incident, Kit decides to seek out Tin Chi, with his whole gang setting his shop house on fire one night. Tin Chi barely escapes alive with his son, while being pursued by the gang and Sadi, a hired assassin. He is offered shelter at Fu's home by Julia, and works at Gold Bar to pay his rent. Angered by the injuries to his son, Tin Chi retaliates and sets Kit's opium den on fire. Kit's sister, Kwan, the head of the syndicate wishing to transition to legal businesses, prevents Kit from taking revenge and visits Tin Chi at the Gold Bar to pay him to drop the matter, but Tin Chi refuses the money, impressing Kwan. At the same time, Tin Chi forges an increasingly close friendship with Fu over their common martial arts past. Kit, attempting to escape from the shadows of his sister Kwan, decides to move into drug dealing with his friend, peddling drugs on Bar Street for Owen Davidson, who uses his restaurant as a front for his drug business. Tin Chi tips off Kwan about the business, who requests for time to settle the matter with Kit. After finding Nana in a back alley, Kit and his gang kill Nana by forcing her to overdose on heroin. Tin Chi and Fu fight their way to the syndicate's headquarters, where they fight with Kit and Kwan. Kwan, attempting to placate them, cuts off Kit's right arm and forces him to reveal the drug storage. Fu then exposes the drugs to the media. In return, Davidson has corrupt police officers set up Fu on a false drug charge. After arresting him, they hand Fu over to Davidson to be killed in an unfair fight. Subsequently, following the discovery that Davidson murdered Fu, Tin Chi gets himself into a fight with Davidson, during which he regains his confidence in using Wing Chun for good. The police commissioner attempts to arrest Tin Chi but is in turn arrested by his lieutenant Fai for corruption. Davidson attempts to escape in the ensuing chaos, but is assassinated by Sadi, who had been hired by Kwan before leaving Hong Kong with Kit. Soon after, Tin Chi reunites with his son and Julia as they eat a meal together in Julia's home.
