To chase his blues away, a reclusive musical theater addict shares his favorite Broadway cast album with the audience. Magically, the 1928 musical comedy The Drowsy Chaperone bursts to life in his apartment as he delivers a running commentary about the show. The musical tells the hilarious tale of a wedding between a popular Broadway starlet and a handsome, tap-dancing millionaire. But will the wedding take place? With a forgetful best man, a scheming ex-producer, two gangsters in disguise, and a perpetually inebriated chaperone, what could possibly go wrong?
