Flag Of Iron is a 1980 Shaw Brothers kung fu film directed by Chang Cheh and starring the Venom Mob.

The respected and noble ‘Iron Flag’ clan are at constant quarrel with their bitter rivals, the notorious ‘Eagles’, who oversee various illegal activities in the town.

When the police arrive at Iron Flag headquarters, no one knows who is responsible for what since there are no suspects, but nevertheless, the cops want to arrest someone to get the case settled quickly.

Eventually, the police offer that while they will not outright charge someone with murder, at least one of the Iron Flag members must take responsibility for what occurred and leave town immediately.

Brother Lo agrees to take responsibility and leave town, at the protest of both Tsao Feng and his close friend, ‘Iron Monkey’ Yuan Lang (Chiang Sheng).
