Brendan Byers III is a rich playboy who enlists to fight in the World War II, but is classified 4F (military conscription). He really wants to fight, so he enlists other 4-Fs and some loyal volunteers from his own service staff and forms his own army. He finances their training and equipment. Once completed, they travel to the front in Italy, with Byers impersonating a Nazi general named Eric Kesselring.
