Master Z: Ip Man Legacy

After being defeated by Ip Man, Cheung Tin-chi lives a depressed life moonlighting as a mercenary before choosing to leave behind martial arts altogether and instead open a grocery store on the ground floor of his house. While on a delivery run, he runs into an opium addict named Nana and her friend Julia who are both fleeing from drug dealer Tso Sai Kit. Tin-chi ends up fighting with Kit's gang and defeats them single-handedly.
The Royal Hong Kong Police Force arrive and arrest everyone. Kit and his gang are released after bribing a corrupt senior police officer, while Nana and Julia are released by name-dropping Julia's brother, Fu, the owner of Gold Bar, one of the most popular bars on Bar Street. Tin-chi is eventually released late at night and is unable to take his son to a steakhouse called Petrus for his birthday.
Following the incident, Kit decides to seek out Tin-chi, with his whole gang setting fire to Tin-chi's building. Tin-chi barely escapes with his son Fung while being pursued by the gang, with the Ma King-sang, who has returned from Frank in Ip Man 3, and Sadi, a hired assassin. He is offered shelter at Fu's home by Julia, and works as a waiter 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 a family crime syndicate wishing to transition to legal businesses, prevents Kit from taking revenge and visits Tin-chi at Gold Bar to compensate him for all damages Kit caused and for Tin-chi to drop the matter. Tin-chi refuses the money, impressing Kwan. At the same time, Tin-chi forges an increasingly close friendship with Fu over their shared pasts in martial arts.
Kit, attempting to escape from the shadow of his sister Kwan, decides to move into heroin dealing. Before he could, he chats with Ma King-sang about plans about the heroin, Tin-chi, Fu and Kwan. Then both of them gave drugs to their men and arrives to Petrus Steakhouse. He peddles his drugs on Bar Street for Owen Davidson, the owner of Petrus, who uses the restaurant as a front for his drug business after a chat with Kit and Ma King-sang. Davidson has plans to work with the Cheung Lok but still convinced when Kit kills Ma by shooting his head. Tin-chi tips off Kwan about the business, who requests more time to settle the matter with Kit.
After finding Nana in a back alley, Kit and his gang kill her 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 where he stores his heroin. Fu exposes the drugs to the media which makes newspaper headlines.
Soon after, Davidson has corrupt police officers plant drugs at Gold Bar and arrest Fu on drug charges. After arresting him, the senior police officer hands Fu over to Davidson to be killed in an unfair fight. Following the discovery that Davidson murdered Fu, Tin-chi fights with Davidson at his restaurant, during which he regains his confidence in using Wing Chun for good.
The senior police officer arrives to arrest Tin-chi despite Tin-chi's testimony that the heroin belongs to Davidson. Instead of complying, Lieutenant Fai arrests his boss for corruption, assault and lets Tin-chi go free. 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.
Tin-chi returns to Julia's apartment and reunites with his son. The three of them share a meal together. In a mid-credits scene, Fung uses Wing Chun to defeat the boy who bullied him earlier.
