Ostensibly a vehicle for RKO Radio's new comedy duo Wally Brown and Alan Carney, Seven Days Ashore actually casts Brown & Carney in subordinate roles. The plotline is carried by furloughed sailor Dan Arland (Gordon Oliver), who while docked in San Francisco gets mixed up with three amorous females. Hoping to avoid breach-of-promise suits from two of the girls, Arland palms them off to his pals Monty (Brown) and Orville (Carney), while he devotes his time to debutante Annabelle (played by future news journalist Elaine Shepard). One of the "castaway" girls is portrayed by Virginia Mayo, on the verge of stardom. Musical relief is provided by Dooley Wilson ("Sam" in Casablanca), Freddie Slack and His Orchestra, and the zany "corn aggregation" led by Freddie "Schnickelfritz" Fisher.
