Emergency Squad

Tomas Milian stars as an embittered Interpol agent haunted by the slaying of his wife and relentlessly stalking the gang of bank robbers responsible. When shell casings from a daring daylight heist match slugs taken from the scene of his wife's murder, Ravelli identifies the shooter as a French thug known as "Marseilles" (Gastone Moschin) and throws away his badge to exact his revenge.
