Bathing-suit manufacturer Eve (Esther Williams) tries to help when her dim sister (Betty Garrett) falls for a masseur (Red Skelton), believing he's Latin polo star Jose O'Rourke. Afraid the truth will crush her sister, Eve locates the dashing O'Rourke (Ricardo Montalban) -- but soon falls in love with him. This musical comedy of errors, which features Williams's trademark water ballets, won a Best Song Oscar for "Baby, It's Cold Outside."
