Singer Lupe Velez (Carmelita) is brought over from Mexico by Donald Woods (Dennis). I'm not sure why - he needs a Mexican singer for a contract of some sort. Anyway, he is given the role of her "protector" whilst she is in the USA and, of course, Velez doesn't play ball. She is, after all, the "Mexican Spitfire" and you will understand why she is called this whilst watching the film. She seems a coarse version of Carmen Miranda, though not as talented. Woods has a fiancée in Linda Hayes (Elizabeth) who does not approve of the new arrival, whilst Velez spends the whole film disobeying instructions with the help of Leon Errol (Uncle Matt). Love is also in the air.
There are many opportunities for misunderstanding in this film as well as the play on the Mexican accent and poor English grammatical structure which provides the bulk of the comedy. It can be funny in parts but that whirlwind of constant energy gets very tedious and Velez is not someone you would wish to keep company with for very long. All the shouting, etc - just stop it and do some proper acting with subtle dialogue, please!
I wish Errol had taken Velez on various evenings out to 'kick the gong around' as she had requested, ie, smoke opium. I've tried it and it is great. It would have calmed her down and possibly added some depth to the film.
