 A scrappy fighter from Jersey City named Tommy Shea -- "born in a dump, educated in an alley" -- catches the eye of wealthy businessman, Robert Mallinson, who allows him to train at his Long Island estate. Shea soon falls for Mallinson s daughter, Dorothy, but fears he doesn t have the money to support her in proper style. To get this money, Shea decides to work with crooked fight-promoter Harry Cram, even though this means dropping his honest manager, Dave Bernstein. As the big fight approaches, however, Shea begins to have second thoughts.
