Guys and Dolls is a musical set in the bustling streets of New York City. It follows the relationships of two unlikely couples: high-rolling gambler Sky Masterson with the pious Sarah Brown, and Nathan Detroit with his fiancée Adelaide. Nathan Detroit is a con-man who is trying to find a new home for his illegal crap game. The musical was adapted from the stage hit of the same name, which was based on writings by Damon Runyon.
