The story is set in New Orleans and David and Pierre (Don Ameche and Robert Young) run a very successful shipping company. However, their retired father keeps spending everything he can get his hands on chasing after young gold-diggers. So, now that he's talking about marrying one of them, the French singer Josette, the pair are determined to bust up dad's relationship.
When the pair arrive at the nightclub where Josette is the headline act, they are unaware that Josette has run off with some other rich guy. Instead, the nightclub owner has another woman, Renee (Simone Simon), fill in for her. She is quite the success...but David and Pierre mistakenly think SHE is Josette! So, for most of the movie, they think she's a money-grubber when in fact she's a nice girl...with a singing voice that will make your ears bleed (though everyone in the film seems to think she sings like an angel).
This is a cute little comedy and is well worth seeing. My only complaint is one small scene where a man is being beaten up by his wife. This was though to be funny back in 1938 but it seems shocking and incredibly unfunny. Oh, how times have changed!
