Courtney Shayne is the manipulative, self-entitled, cruel, vindictive and sociopathic leader of an all-female quartet, "The Flawless Four" in Reagan High School. Together with two other friends, she kidnaps her rival, Elizabeth "Liz" Purr, as a prank. Courtney stuffs a
jawbreaker into her mouth, gags her, and puts her into the trunk of a car. Later, the girls open the trunk and discover Liz is dead, having choked to death on the jawbreaker. Liz's best friend, Julie, wants to go to the police, but Courtney forbids her. Courtney spins an endless web of lies to cover up the murder and maintain her popularity. When Julie breaks away from the clique, she becomes a target for abuse and contempt throughout the school. Julie discovers, however, a recording in which Courtney admits to killing Liz, and the truth is made public just as Courtney is crowned
prom queen. This angers the entire student body, who soon gangs up and turns her in to the authorities, blocking any paths of escape. ==Characterization==
