“Curtains” is a suspenseful musical comedy, featuring a Golden Age-style score by the legendary songwriting duo John Kander and Fred Ebb — the minds behind “Cabaret” and “Chicago.”

Butler Area School District’s show combines the best elements of classic Broadway with a clever whodunit twist that will keep audiences laughing and guessing until the very end.

Set in the brassy, bright and promising year of 1959, Boston’s Colonial Theatre is playing host to the opening night performance of a new musical. When the leading lady mysteriously dies on stage, the entire cast and crew are suspects. Enter a local detective, who just happens to be a musical theater fan, said a synopsis from the musical’s director, Dale VanLaningham.
