Amber Pollock, a mean, snobbish, virgin and popular high school senior, dies after being named Prom Queen at her senior prom when her crown ends up electrified after an accident with her boyfriends car. While in limbo, an angel named Supervisor J-3 gives her the task of returning to her high school as a ghost to arrange that the school's least-popular student Lisa Sommers becomes Prom Queen in her place within one week at the makeup prom. When Lisa becomes Prom Queen, Supervisor J-3 will have Amber forgiven of her past actions and send her to Heaven. Supervisor J-3 also tells Amber that if Lisa doesn't become Prom Queen by the deadline, Amber will be on the next shuttle bus to Hell.Amber is sent back to Earth as a ghost where she materializes at her memorial service and appears to Lisa afterwords who at first refuses to believe that Amber is appearing before her (Note: the running joke is that no one, except Lisa, can see or hear Amber). Amber manages to inform Lisa about her situation but things do not go as planned. Lisa explains that she doesn't want to be crowned Prom Queen and has no desire to be popular or be noticed in any way. After Amber convinces Lisa that she can get her attention from her crush, Nick Ramsey, Amber insists they should go shopping to get Lisa some new outfits for school and the prom. During their shopping spree, Amber learns that she can magically change her own clothes just by wishing for the outfit she has on. Their plans for Lisa running for Prom Queen becomes complicated as Amber's former friend, Carlita Cache, decides to run and starts dating Nick.When Carlita decides to throw a house party, Amber and Lisa decide to mess with Carlita's plan by changing the party's date and sending this change in an email from a school computer to everyone's phone at their high school. With Carlita's party plans ruined, Amber and Lisa plan a party at Lisa's house the same night since her parents are away at a spa treatment. During the party, Amber gets Lisa up on stage to sing "Typical" which attracts the attention of Nick. Lisa and Nick talk after her performance and the two end up sharing an unexpected kiss and Nick then tells her he will break it off with Carlita.Amber and Lisa soon find out from Vice-Principal Richardson that Lisa's friend, Raj Kurkuri, who was trying to buy a used calculator online, accidentally forgot to log off on a school computer before Lisa sent the changed party date message, and Raj is held responsible for the damages at Carlita's house. Lisa ends up passing on her friends' plans for finishing a 'claymation' pig film now that she is popular.Meanwhile, Amber's younger sister Clementine feels her mother is too busy mourning the death of Amber to pay any attention to her. Seeing this for herself, Amber helps guide her mother into paying more attention to Clementine now that she has died.Lisa's friend, Selena, learns about the ghost Amber's involvement with Lisa's popularity and decides to use black magic to tell Amber to leave Lisa alone, but Amber tells her she needs to right what she did wrong in order to get into Heaven. Selena is understanding but still pleads for Amber to help Lisa return to normal. Amber confronts Lisa and, realizing that she has unintentionally ruined her life by making her popular, jumps into her body to drive her out to Oak Springs on Highway 7 (out in the middle of nowhere) so she would not make it back to town in time for the prom that evening. After stumbling onto Floyd's Gator Jerky Shop, and calls all her friends on a pay phone, Lisa is unsuccessful in getting a ride back into town until she reaches Selena. When Selena (along with Raj and Collin) make it to pick her up, Lisa learns being popular isn't what it is cracked up to be. She also learns Raj was suspended and has to perform community service to fix Carlita's yard. Meanwhile, Amber reports her failure to Supervisor J-3 and takes a ride down to Hell in a flaming prison shuttle bus.After just making it to prom night, Lisa confesses to her vice principal and the rest of the school that it was her that sent the mass email about the change to Carlita's party, not Raj. She then makes a speech on stage that everyone should break down the class barriers between the popular and unpopular by voting Raj as Prom King which almost all of the students agree upon. After Raj is elected Prom King, Amber is transported off the shuttle bus to Hell to get her wings to enter Heaven as the least popular student was voted Prom King. She appears to Lisa one last time and the two share a hug with Amber promising to watch over Lisa from Heaven before she goes. Carlita (angry that she didn't get crowned Prom Queen) tries to stop the music by pulling wires from the stage's control box electrocuting herself in the process. Then Supervisor J-3's voice can be heard saying "Here we go again."
Output: Question: Who is angry that she didn't get crowned Prom Queen?, Answer: Carlita
