Shy girl Angelique Hennessey gets invited to a party by a guy she fancies in Bad Reputation (2005). He has an ulterior motive however, and is just luring her there so that he and his friends can rape her.
On the night in question he plies her with alcohol and leads her to a bedroom. When she’s sufficiently drunk, he lets his friends into the room and turns up the music to drown out her cries. Then he and his pals take turns forcing themselves on her.
After the incident she is branded a slut by everyone else at school, who don’t believe her story, and so she sets about planning a bloody revenge on those who sexually assaulted her and those who didn’t believe her.
