Fury of the Dragon (Meng long guojiang) (1972)

This movie takes Kato (Bruce Lee) and the Green Hornet (Van Williams) on four epic adventures as they battle against the forces of urban evil. Their first task is to stop a plot to overthrow a young prince of foreign power. Secondly they must expose two crooked cops, a case that leads to the Green Hornet being injured, and nearly killed. Kato and the Green Hornet are then pushed to the very limit by a well-organised gang carrying out a million dollar art robbery, and using an extraordinary ray gun to eliminate anyone in their path. Finally, our heroes must dwell into the dark underworld of drug trafficking, testing all their skills in crime fighting.
