After graduating from Pacific Night Law School in Los Angeles, feisty and ambitious Mexican American Johnny Ramirez loses his first court case because he is ill-prepared. His poor, Hispanic client's truck was destroyed by careless debutante Dale Elwell. Johnny is harassed by the opposing attorney, uppercrust Brook Manville, who is defending his lover, Elwell. Johnny reacts, losing his temper and the case. Disbarred for his actions, he journeys to a small town south of the border and finds work as a bouncer, in a seedy casino owned by Charlie Roark. Johnny helps transform the dive into a first-class nightclub called the Silver Slipper that attracts an upscale crowd, and Charlie makes him a partner to reward him for his efforts.
