The Irish in Us
Like any brothers, Danny (James Cagney) and Pat (Pat O'Brien) have had their share of differences. But the sibling rivalry gets pumped up to the next level when lovely Lucille (Olivia de Havilland) comes between them. Pat, a police officer, is planning on marrying Lucille, but only if he can trust Danny to take over the financial support of their mother. But when Danny instead risks it all to be a boxing promoter, and starts romancing Pat's girl, the gloves finally come off.
