Por Um Amor (1950)

Prizewinning boxer Johnny Monterez is mad at the world, feeling persecuted because of his Mexican heritage. Worse yet, his right hand is damaged from years of fighting. Then Johnny falls in love with Pat O'Malley, his manager's pretty daughter, even though his best friend, Rick Gavery, is already besotted with her. Everything is on the line when Johnny, against Rick's wishes, agrees to a match with a fearsome opponent.
