Amber Pollock (Cassie Scerbo), a mean, snobbish, popular high school senior, dies after being named Prom Queen when she was picking up a crown that was electrified after an accident with her boyfriend's car. While in Limbo, an angel (Tim Gunn) gives her the task of returning to her high school as a ghost in order to transform the school's least popular student Lisa Sommers (Lindsey Shaw) into the next prom queen at the makeup prom. If she succeeds, she will be sent to Heaven, and if not, she will be on the next Shuttle bus service to Hell.
