A "mama's boy" falls for a spinster who takes care of children at a department store nursery.

Based on Dowling's 1925 stage vehicle of the same name, the story is set in motion when the king of the mythical European nation of Bulgravia visits an American health resort. Hero Tim Dugan appoints himself the king's unofficial protector, saving him from the larcenous designs of crooked gambler Arnold Bookstein.
