During the dispute of the box championship, the boxer Ernie Driscoll loses the fight and the champion damages his optic nerve. Ernie is forced to quit his career and becomes a taxi driver in New York. His wife Pauline Driscoll blames him for their simple life and their relationship is not good. The quick-tempered Ernie usually meets his friend, the aspirant actress Linda James, at the bar where he drinks coffee late night. Pauline has a love affair with the elegant thief Victor Rawlins and she helps him to steal a fortune in diamonds from a man called Dutch. Meanwhile Linda lures Ernie to be cast in a play but when she learns that the producer has accused Ernie to the police to promote his play, she regrets and decides to help him. Meanwhile Victor kills Pauline to sell the jewels to a powerful fence and frames Ernie so that he can travel abroad. Now Ernie and Linda need to track Victor down to prove his innocence, but the fence and his gang are also chasing Victor to kill him.—Claudio Carvalho, Rio de Janeiro, Brazil
