In this crime drama set on the seedy waterfront of San Francisco, a longshoreman studies in his spare time to become an aircraft mechanic. He is also in love with a barmaid who works at her father's saloon. One day at the bar, the longshoreman gets into a fight with a man who is later found dead. Naturally, the longshoreman becomes the prime suspect and is arrested. There are two men who can prove him innocent, but they are in league with the real killer, a fugitive from Alcatraz. Meanwhile, a priest, a drunk, and the girl's father try to prove that the longshoreman is innocent by finding the fugitive's wife. The barmaid and the trampy wife then get in a big fight. In the end, the priest and the fugitive wrestle it out and the thief gets his just desserts.
