Chicago: Teen Edition is a family-friendly adaptation of the classic musical Chicago, set in the Roaring Twenties, about ambitious chorus girl Roxie Hart and vaudeville star Velma Kelly, both "Merry Murderesses" in Cook County Jail, who compete for fame and acquittal with the help of slick lawyer Billy Flynn, all while exposing themes of celebrity obsession, media manipulation, and the corrupt justice system, with modified language and mature content to suit younger performers and audiences.
