Edward G. Robinson turns his gangster image on it's head and laughs spill from the pockets in a gleeful romp based on the Broadway farce penned by Laura and S.J. Perelman. Robinson plays Pressure Maxwell, who emerges from Sing Sing planning to run a dog track with cronies Jug (Broderick Crawford) and Weepy (Edward Brophy). But a plan needs dough, so the fellas (assisted by Jane Wyman) open a luggage shop as a front while attempting to tunnel into the bank next door. Now add the stores unexpected success, a gabby traveling valise salesman (Jack Carson) and the arrival of a sour con (Anthony Quinn) who wants in on the action, and the laughs are thick as thieves.
