**SPOILERS** Nothing special here but a young beautiful Ann Sheridan as Flo Allen the love interest for the film's star John Litel as the hard as nails gangster and racketeer with a heart of gold ""Gat"-in that he always "gets" what he wants-Brady.
In a world of death and violence Gat never went as far as having anyone of his many enemies iced, or knocked off, not only because it wasn't right but most off all bad for business. It was when one of his henchmen Red Carroll, Ben Weldon, asked Gat to hide out his kid hit-man brother Butch, Matty Fine, that Gat told him to get lost and stop bothering him. Gat knows very well if he did that he'll have the law that he mostly has in his hip pocket, by paying judges D.A's and eye witnesses off, bearing down on him. With Butch getting caught and later sent to the chair for 1st degree murder Red swore to get back at Gat for not coming to his brother's aid.
As things tuned out Red didn't have to wait long with Gat indited on tax fraud and sent to Leavenworth for five years even though he was promised by the state D.A that he'll only get one year if he cooperated with the court! It was later in Leavenworth that Gat ran into Red, who was waiting there for him, and in a wild slug-fest that Red initiated Gat ended up being sent to the "Rock" Alcatraz with his chances for an early release, from 2 1/2 instead of 5 years, no longer possible. Meanwhile Red as if he were Gat's shadow gets himself transfered to the "Rock", by getting into a fight with a prison guard at Leavenworth, just to get under Gat's skin! There's also an interesting sub-plot in the movie involving Gat's 18 year-old daughter Ann or Annabell, Mary MaGuire, who's been kept in the dark, in an exclusive girls school, about her mobster father criminal activities.
***SPOILER*** It was Ann whom the vindictive Red tried to unsuccessfully kidnapped that got him sent away to both Leavenworth and the "Rock" in the first place. Later it was Ann who by getting romantically involved with the New York City District Attorney George Drake, Gordon Oliver, who put her dad behind bars that eventually had him vindicated with an early release in the murder of Red Allen. The very same guy who not only kidnapped Ann but was willing to go so far as implicated Gat in his own murder, in a death bed accusation, despite Gat being completely innocent in his death!
P.S In what has to be a first of its kind Gat who was facing the death penalty was saved by an undercover FBI agent who not only tracked down the person who really murdered Red but had his confession secretly recorded, on a newly invented recording-like Dictaphone, just before he hung himself in his prison cell.
