1942. Corporal Michael Satariano has returned to Chicago a hero, a survivor of the hellish nightmare called Bataan and the first Congressional Medal of Honor winner of WWII. But his war is far from over.
As a boy, before the kindly Satarianos adopted him, Michael traveled with his father, Michael O'Sullivan, Sr. - the feared enforcer for Irish "godfather" John Looney - wreaking a terrible vengeance on those who slaughtered young Michael's mother and brother. Now, with the blessing of Eliot Ness, the decorated son will finish his late father's bloody mission, taking on the powerful criminal organization built by Al Capone and ruled by the ruthless Frank Nitti. But to destroy his enemies, Michael must abandon his small-town sweetheart, survive the affections of a big- city siren, and join forces with those he seeks to destroy - though once the Devil owns a soul, he never gives it back.
