Ma femme, ma vache et moi (1952)

Marinette, the wife of Mario, a sympathetic hobo, is disgusted with the farm and runs off to Paris without husband or child. The tenacious husband sets off in pursuit, accompanied by the baby and a cow that's a bit cumbersome. The unfaithful woman wanted to become a star. Mario and his crew go from music hall to nightclub until finally, a classified ad brings back a repentant Marinette, just in time to prevent Mario from running off with a prostitute, herself eager for a change of scene.
