When Paul Harvey and Jed Prouty formed their oil partnership, one of the clauses stated that when Prouty's daughter (he didn't have one at the time) married Harvey's son in Havana within a month of her 21st birthday, they would get one third of the business. Now she has turned 21, so it's off to Havana, looking for the escape clause that if one refuses, the other gets the oil wells. Dennis O'Keefe plans on going through with the marriage at his father's instance, unless he can get this girl he has never met to dislike him. Jane Frazee's plan is more elaborate. She hires acrobatic dancer Betty Kean to masquerade as her, while Frazee plays her secretary. Miss Kean's limberness will fascinate O'Keefe, he'll marry her and lose the oil wells.
Except when they are taking the train to Havana -- yes, they're coming from New York. Don't expect me to understand it -- O'Keefe and Frazee meet under their fake names and fall in love.
It's a very pleasant romantic comedy, in no small part because whenever director John Auer feels a need to distract you, there's a good comic dancing interlude. Miss Kean is an excellent eccentric dancer. She does a few moves on her own, but in one she's paired with an excellent Black tap trio called 'The Three Chocolateers', and in another with Eddie Foy Jr., who's funny as a busted British count.
