Fourteen-year-old Melinda Sordino begins her freshman year in high school and struggles on the first day. She doesn't have any friends to hang out with, and appears awkward and uncomfortable when speaking to others. Throughout the day, she is made fun of by several students, repeatedly called a "whistleblower". A series of flashbacks reveal that she called the police to a house party during the previous summer. Her actual reason for calling 9-1-1 was that she'd been raped by a senior student at the party, Andy Evans, but her trauma prevented her from reporting the rape over the telephone or when the police arrived.
