Mean Girls is a rock musical with a book by Tina Fey, lyrics by Nell Benjamin, and music by Jeff Richmond. It is based on the 2004 film by Mark Waters, which was also written by Fey and was in turn inspired by Rosalind Wiseman's 2002 book Queen Bees and Wannabes. The musical focuses on Cady Heron, a teenage girl who transfers to a public high school after being homeschooled her whole life in Africa. At school, she befriends outsiders Janis Sarkisian and Damian Hubbard who persuade her to infiltrate the "Plastics", a clique consisting of wealthy but insecure Gretchen Wieners, sweet but dimwitted Karen Smith, and "queen bee" Regina George.
