A Fist Within Four Walls

YING-FUNG meets up with other gangs secretly. He agrees to assign one street to them for illegal business. TAK-LIU and BO-FUNG rush to the welfare association to inform CHIU YEUNG. When CHIU YEUNG leaves, YING-FUNG and CHUK-LUEN appear. CHUK-LUEN reveals that it is not good to have two leaders in the welfare association and he suggests to select the leader by contest. KIT-LUN tells TIU LAN that YING-FUNG and CHIU YEUNG will have a contest. He asks her if she is willing to leave the walled city after the contest. In the midnight, CHIU HA suddenly remembers ZIT-KEUNG's blood pattern and she discovers a big secret. CHIU HA tries to tell CHIU YEUNG the source of the drugs but she discovers that somebody is following her. CHIU HA is not as strong as the man in black but CHIU YEUNG arrives to rescue her on time. CHUK-LUEN reminds YING-FUNG that he should fight with CHIU YEUNG for the leader position.
