Alain Lefevre is actually really just a boxer paid by way of a Marseille mobster to have a dip. If the fight is won by him he attempts to flee America with all the mobster's girlfriend Katrina. This course of action fails by connecting the foreign legion and he seeks escape. As part of this legion he tangles with bonds and abusive lieutenant Steinkampf together with Mackintosh, legionnaires Luther and Rosetti.
