Set in Damon Runyon’s mythical New York City, Guys and Dolls follows the intertwining lives of two main couples: Nathan Detroit, a lovable but chronically broke gambler trying to set up "the oldest established permanent floating crap game in New York" and his fiancée of 14 years, Miss Adelaide, a nightclub dancer tired of waiting to get married. Desperate for money, Nathan bets fellow gambler Sky Masterson that he cannot convince the "Save-a-Soul" Mission's straight-laced Sergeant, Sarah Brown, to go to Havana, Cuba with him.
