A Fist Within Four Walls (TV Series)

In 1945, Bajiquan masters Duen Tung-tin and Chiu Mang-san form a brief alliance to protect the once-peaceful Kowloon Walled City from falling into the hands of ruthless gangs. The alliance breaks when Duen is poisoned and beaten to death by a mysterious assailant, and Chiu is suspected to be the killer. Chiu allegedly commits suicide, his children separates, and the walled city falls under the control of triads. Fifteen years later, Chiu's now adult son Chor Au-kuen returns to the walled city to find his long-lost sister. Concealing his true identity as a Bajiquan practitioner, he gets acquainted with Tiu Lan, the lady boss of a local hair salon, and finds a job as a water labourer so he can pay his rent. By chance, Kuen meets the dentist Duen Ying-fung, the only son of Duen, and finds that the Duen family has now closed down their Bajiquan kwoon and started a dental clinic. Fung is skilled in Bajiquan but only trains it in secret, as he does not want to be seen as a threat against the city's leading triad organisation, The Association.
