A Balkan prince making an official tour of the United States jumps off the train to mingle with the common people and experience the "real" America. Prince Henry (Dennis Morgan) befriends a cabbie from Brooklyn named Buzz Williams (Jack Carson) and gets a street-level view of New York City with the help of Buzz's family and friends.
The prince particularly enjoys seeing the sights with Buzz's girlfriend, Connie (Joan Leslie), who is a manicurist. In a short time, they grow very close, setting up a romantic triangle that is the crux of the film. All three characters are very likable and the romantic complications are kept light. In fact, Buzz and Connie have an unusual relationship. When Connie has to make a choice between the two gents, it is handled very well.
Within the story are plugs for democracy (in the immediate aftermath of the world war). This coincides with the beginning of the American effort to export its political system.
Warner Brothers also used the film to promote its upcoming film, "The Big Sleep", which would be released later. This is done cleverly and humorously.
The entire cast is fun to watch. Carson and Morgan might not be the studio's answer to Crosby and Hope, but they have a chemistry that works well. They will later appear in "Two Guys from Texas".
