Douglas MacLean, who made his mark during the 1920s as a light comedian, stars as a Marine sergeant in this comedy-drama, which he co-produced with Paramount. The studio must have seen this picture as a sure bet at the box office -- MacLean's first breakthrough picture in 1919 was 23 1/2 Hours Leave and Wallace Beery and Raymond Hatton were currently reaping in the bucks in their Army picture, Behind the Front. Let-It-Rain Riley (MacLean) is a devil-may-care Marine sergeant who falls in love with a girl (Shirley Mason) who he assumes to be rich. His rival for the girl's affection is his pal, Kelly (Wade Boteler). The guys find out that the object of their affections is but a modest switchboard operator but she proves to be invaluable when she deciphers a code and discovers that a mail train is about to be robbed. Riley takes care of the crooks, but not before a thrilling climax in which the mail car is cut loose from the train. Riley manages to make good, winning both a promotion to lieutenant and the girl.
