Set in 1929/1930 Berlin during the twilight of the Jazz Age as the Nazis are ascending to power, the musical focuses on the hedonistic nightlife at the seedy Kit Kat Klub and revolves around American writer Clifford Bradshaw's relations with English cabaret performer Sally Bowles. A subplot involves the doomed romance between German boarding house owner Fraulein Schneider and her elderly suitor Herr Schultz, a Jewish fruit vendor.
