In this action-packed slapstick comedy - a dying mob boss nicknamed "The Mexican" asks his old friend and ex-gangster, Fernand Naudin (Lino Ventura), to come out of retirement to take over the family businesses and protect his soon to be married daughter. The rival families take an exception to this and unleash their henchmen to take care of Naudin, but they get much more than they bargained for. After surviving their first onslaught, he declares war on the other families and their shady operations. The stellar cast includes Bernard Blier and Francis Blanche with great direction by Georges Lautner and writing by Michel Audiard. The writer, director and three leads reappeared the following year in the even more successful Spy vs. Spy comedy, The Great Spy Chase (Les Barbouzes).
