Based on the Tony Award-winning Broadway musical,NBC’sHairspray Live!takes place in 1962 Baltimore. Teenager Tracy Turnblad’s dream is to dance on “The Corny Collins Show,” a local TV program. When, against all odds, Tracy wins a role on the show, she becomes a celebrity overnight and meets a colorful array of characters, including the resident dreamboat, Link; the ambitious mean girl, Amber; an African-American boy she meets in detention, Seaweed; and his mother, Motormouth Maybelle, the owner of a local record store. Tracy’s mother is the indomitable Edna Turnblad, and she eventually encourages Tracy on her campaign to integrate the all-white “Corny Collins Show.”
