Dan Hardesty is an escaped murderer, sentenced to hang and on the run. In a
Hong Kong bar, he literally bumps into Joan Ames, a terminally ill woman whose friends are wishing her bon voyage. It is love at first sight. In what will become a signature gesture for the couple, they share a
Paradise cocktail, then Dan breaks the bowl of his glass, followed by Joan; they leave the stems crossed on the bar.
San Francisco Police Sergeant Steve Burke captures Dan at gunpoint when he leaves the bar (though out of sight of Joan) and escorts him aboard an
ocean liner bound for San Francisco. Dan jumps into the water, dragging Steve with him. He takes the handcuff key from Steve's pocket and frees himself. Then he spots Joan among the passengers looking over the rail at them. He rescues floundering non-swimmer Steve rather than escape. Once the ship is underway, he persuades Steve to remove the handcuffs. Dan and Joan fall in love on the month-long cruise, neither knowing that the other is under the shadow of death. By chance, two of Dan's friends are also aboard, pickpocket Skippy and con artist "Barrel House Betty", masquerading as "Countess Barilhaus". The countess distracts Steve as much as she can to help Dan. Just before the only stop, at
Honolulu, Steve has Dan put in the brig, but Dan gets out with their help and goes ashore to arrange escape on a steamer leaving that night. Joan intercepts him as he leaves the ship, and they spend an idyllic day together. When they drive back to the dock that evening, Dan starts to tell her why he cannot return to the ship, but she faints. Dan carries her aboard for medical help and stays by her side, forfeiting his chance at escape. Later, Joan's doctor tells Dan about her condition and that the slightest excitement or shock could be fatal. Dan tells the doctor the truth about himself. Meanwhile, a romance blooms between Steve and the countess. When they near the end of the voyage, he awkwardly proposes to her. He wants to give up being a cop and live on a chicken ranch he owns. (Earlier in the film, Betty told Skippy that she dreamed of giving it all up and buying herself a chicken ranch.) She starts to tell him her true identity, but her confession is interrupted when a steward delivers a telegram to Steve. It is from his boss, telling him to find notorious con-woman Barrelhouse Betty and bring her in. He says nothing, as he still wants to marry her. They kiss, and Steve throws the telegram overboard. Steve and Dan get ready to disembark, an overcoat draped over the handcuffs that link them. On an impulse, Joan goes to their cabin, where a steward who overheard the grim truth tells her about it. She frantically searches for Dan, and finds him with Steve. The two lovers part for the last time without letting on that they know each other's secret, and Joan collapses after Dan is out of sight. They had agreed to meet again a month later, on New Year's Eve, at a bar in
Agua Caliente, Mexico. At the appointed time and place, the dance floor is full, but the long bar is empty except for Skippy, standing solemnly at one end, and two bartenders at the other. The bartenders are startled by the sound of glass breaking. They turn to find the crossed stems and shattered pieces of two cocktail glasses lying on the bar. They glisten there for a moment and then vanish. ==Cast==
