'9 to 5 The Musical' tells the story of three unlikely friends who take control of their office and learn there is nothing they can't do, even in a man's world. With music and lyrics by Dolly Parton and book by Patricia Resnick, 9 to 5 is based on the 1980 hit movie. Set in the late 1970s, this hilarious story of friendship and revenge in the Rolodex era is outrageous, thought-provoking, and even a little romantic.
