Real-life kung fu master Nathan Ingram stars in this gritty, low-budget martial arts epic as a local karate school owner who clashes with a gang of drug traffickers posing as the owners of a rival dojo. Director Charlie Ahearn (who helmed the landmark hip-hop film Wild Style) used the housing projects next to his New York Lower East Side apartment as his central location in this 1979 classic, shot on a vintage Super 8 camera.
