Next year Fiorello is campaigning for Congress, and Thea introduces him. Fiorello promises to break the stranglehold of Tammany Hall ("The Name's LaGuardia!"). LaGuardia wins the election ("The Bum Won"). In another year, LaGuardia enlists in the Air Force and proposes to Thea. He and Marie say their farewells as he is about to leave for the war ("Till Tomorrow"). LaGuardia's participation in the war is presented as a series of montages, staged and on film. With the war over, Fiorello returns home ("Home Again"), with both Marie and Thea waiting for him. He goes to Thea, who has agreed to marriage. Morris, the office manager, comforts Marie.
