A Fist Within Four Walls (2016)

Bearing the grief of losing his family, Chor Au Kuen returns to the Kowloon Walled City in hopes of finding his long-lost sister, only to find that the very place he grew up in has become a lawless no man’s land. Concealing his real identity as a Bajiquan master, Au Kuen creates a new identity and gets acquainted with the feisty and sassy Tiu Lan, the lady boss of a hair salon; Duen Ying Fung, a dentist; and But Tak Liu, a water worker. Au Kuen also impresses the highly skilled martial artist Yuk Bo Fung, who owns a store across the street from Tiu Lan’s hair salon. To restore law and order in the walled city, Au Kuen unites everyone to form a welfare association to resist the triads. However, this decision causes a clash between him and Bo Fung’s son Lung Shing Fu, who is an underground Muay Thai fighter. Just as things are finally getting on course, a key figure in a powerful triad mysteriously dies under the hands of a Bajiquan master. Au Kuen and Tiu Lan investigate, and their investigation leads them to Fa Man, the leader of a stripping dance troupe. But one discovery leads to another, and Au Kuen finds himself uncovering the truth behind his father’s death. The burden behind his family’s mystery may have been lifted, but not all is well. Au Kuen still carries one more painful memory that he’s unable to let go of — that the one he trusts the most is actually a member of a gang of ruthless assassins.
