A man shares with the audience his favorite record – the 1928 musical The Drowsy Chaperone. As he plays the record, the show comes to life in his apartment. Mix in two lovebirds on the eve of their wedding, a bumbling best man, a desperate theatre producer, a not-so-bright hostess, gangsters posing as pastry chefs, a misguided Don Juan and a sleepy chaperone, and you have the ingredients for a show that will have everyone laughing.
