Two crime families battle for supremacy in 1929 Chicago in this Italian crime spoof. One group, known as the "Sons of Mammasantissima" thereby professes its (ironic) dedication to the Virgin Mother. The other family works undercover from a Salvation Army soup kitchen. Neither family seems capable of accomplishing anything of note until a wily Sicilian arrives on the scene and sorts things out.
