As it turns out, the story is a romantic comedy about Willie, a lowly department store clerk who unwittingly sponsors a orphaned boy. He wants to continue being the boy's benefactor, because he has eyes for the pretty nurse, but the weekly cost of his new ward is more than his humble salary allows. With a little ingenuity, and the help from his gum-chomping pal Aggie, he finds a way to keep up his charade. . .because of course the pretty nurse assumes him to be a wealthy businessman.
The leading actor is Eddie Quillan, who links this blog post to yesterday's in that he later went on to star in The Grapes of Wrath (1940) alongside Jane Darwell. Quillan's career began in vaudeville and in silent films. He does resemble The Tramp, but with a baby face.
