Moon Over Miami

The Latimer sisters learn their expected inheritance of $55,000 has been reduced to $4,000 after taxes and fees. This jaw-dropping news spurs Kay to redefine her plan, aiming to marry into wealth rather than hope for a lucky windfall. The moment sets the stake for their upcoming Miami scheme.

Kay convinces Susan and Barbara to invest their money in a trip to Miami to seek wealthy husbands. They adopt disguises—Barbara as Kay's secretary and Susan as her maid—to help Kay's scheme. The plan shifts from theory to action as the trio prepares to leave Texas for Miami.

The trio checks into the Flamingo Hotel and soon meets Jack O'Hara, a bartender who rails against fortune-hunters. Despite his cynicism, he is drawn to Susan, complicating the ruse. Kay tests the waters in the hotel while hoping for legitimate romance to bloom.

Kay lands an invitation to a party hosted by Jeff Bolton, a rich mining heir, and encounters Phil O'Neil at the event. The two men become rivals for Kay's attention, launching the competition that drives much of the plot. Barbara watches with mixed interest as the men jockey for position.

Barbara falls for Jeff, further intensifying the love triangle and complicating Kay's choices. The rivalry between Jeff and Phil deepens as they vie for Kay's hand. Kay's hopes flicker between sincerity and her original plan for a wealthy match.

After three weeks, the women face an unaffordable hotel bill; Susan borrows money from Jack, who has proposed to her. To secure a successful outcome, Kay arranges a pretext of romance-likelihood by orchestrating a dance that could force one of the men into proposing.

Kay stages Barbara's dance with Jeff to keep him occupied while she talks with Phil, whom she has fallen in love with. Phil admits he's broke and warns that the O'Neil Mines won't pay off for years. Kay admits her original motive and agrees to pursue other partners, altering the course of the evening's game.

Phil tells Jeff that Kay loves him, prompting Kay to accept Jeff’s marriage proposal. The alliance appears to settle the matter, though the emotional groundwork remains unsettled as the trio navigates deception and genuine feeling.

As the women prepare to leave for Jeff's father's island, Jack overhears their scheme and threatens to reveal the truth to Jeff. They lock Jack in the bathroom before heading to the island, where more complicated loyalties await in the presence of Jeff's father.

On the island they meet William, Jeff's businessman father. Phil travels there to serve as Jeff's best man, hoping to secure his place with Kay. Jack reappears, pressing his threat and adding tension to the lovers' gambit.

At Jeff's party for Kay, Barbara urges Jeff to take a job in South America to escape his father's shadow, while Phil confesses his love for Kay. Jeff enters, and the scene culminates with the understanding that Kay and Phil plan to marry. The emotional landscape is reshaped as loyalties realign.

In a final twist, Jeff reveals he has loved Barbara all along and will marry her. Kay and Phil declare they will marry, and Susan and Jack also find happiness together. The story closes with three couples beginning their lives together, resolving the romantic caper on a hopeful note.
