Neptune's Daughter

Joe Backett and Eve Barrett operate the Neptune Swimwear Company; Eve is its chief designer and swimsuit model. Eve's scatterbrained, man-hungry sister Betty Barrett works with them. Joe, who is in love with Eve, suggests that they put on an underwater spectacle in honor of a visiting South American polo team captained by Jose O'Rourke. When inexperienced Betty goes to the polo field looking for a visiting polo player with whom to fall in love, she meets who she believes is Jose, but she's actually met Jack Spratt, the equally-inexperienced local masseur for the polo teams. Jack does not correct Betty's misconception as he believes she would never date a regular fella like him. Wanting to protect her inexperienced sister from an experienced South American athlete, Eve forbids the actual Jose to date Betty. Jose, having never met Betty, agrees only on the condition that Eve go out with him instead. For Jose, it's love at first sight with Eve. Things get complicated when Betty and Jack (pretending to be Jose) get serious, and Eve and Jose get serious, with Joe wanting to get Jose out of the way, and Eve not wanting to feel anything for Jose if only to protect Eve from getting hurt. A local mobster who thinks he can make some easy money if Jose doesn't show up for the scheduled polo match further complicates the proceedings.
