It all begins with a bet.
New York, the city that never sleeps. And within it, all human life. From the news seller to the chorus girl, from the gambler to the missionary - all of them caught up in the teeming vitality of the city streets.
"Guys and Dolls" is a fable about what happens to gambling men and the women who long to tame them. Set in the colorful world of New York City in the mid 20th century, the romantic and funny "Guys And Dolls" is populated with gangsters and gamblers, missionary dolls and scantily clad showgirls, and one the greatest musical scores in the history of American theatre.
Nathan Detroit is desperate to find a location for his floating crap game. He can use the Biltmore Garage, but only if he can come up with a thousand dollars - and quickly. He has to find a bet that he can win against Sky Masterson, and succeeds in wagering that Sky cannot persuade Sergeant Sarah Brown to fly with him to Havana. Sky realises that he has been conned, but won't give up without trying. He uses his considerable charm to convince Sarah that he is reformed sinner, and that he will deliver a dozen sinners to her Mission if she will have dinner with him at his favourite restaurant. She reluctantly agrees, without realising that the restaurant is in Cuba.
Adelaide hasn't given up hope that Nathan has given up his shady lifestyle, and that their fourteen year long engagement will soon end in wedding bells. However, Nathan shows no signs of any change in his mode of employment, and during Sky and Sarah's absence in Havana, organises his game in the Save a Soul Mission itself. To convince the local policeman that the gathering of gamblers is entirely legitimate, Nathan is forced to announce that he and Adelaide are eloping that evening. In Cuba, Sky sees Sarah in a completely different light, and despite the undoubted opportunity, the better side of his nature prevails. As they return from Havana, the crap game is raided, and Sarah runs from Sky, believing herself to have been used in order to get her away from the Mission.
Nathan cannot elope and run the crap game, so he lets Adelaide run once more. Sarah's uncle Arvide realises that she has fallen in love with Sky, but refuses to have anything to do with him. Arvide insists that Sky fulfil his promise to deliver twelve sinners to the Mission. At the crap game, Nathan offers to pay up on his bet about Sarah and Havana, but Sky denies that he took her there. Sky rolls the dice to win the souls of the crapshooters, and insists that they keep their promise to attend the prayer meeting.
Adelaide forgives Nathan on condition that they elope, but Nathan has the most unbelievable excuse of all - a prior engagement at the prayer meeting. At the meeting the gamblers reluctantly confess to their previous sins, and Sarah's mission is saved from closure. All ends happily as Nathan and Adelaide marry at the Mission now run by Sergeant Sarah and Brother Sky Masterson.
