Heather (Mary Elizabeth Winstead) is the spoilt rich sister. She does not agree with the tradition of buying the famous serial killer Billy, whom used to live in the very sorority house she does, a christmas present. Heather complains alot and is not considerate of others when the murders begin, only thinking of herself. She suspects a fellow sorority sister for the killings, and while investigating finds newspaper articles and a doll in the sisters room. However Heather later discovers this sisters dead body. After doing so, she insists that they all leave. However many characters would rather stay as they feel they need to wait for the missing sisters to turn up. Heather leaves alongside Mrs. Mac (Andrea Martin) to go and get help. While in the car, Mrs Mac tells Heather to scrape the ice and snow of the windows, but Heather refuses to do so, much to the anger of Mrs Mac. As Heather remains in the car, Mrs Mac scrapes the windows, only to see an eye watching her. Suddenly the car jolts and blood is sprayed across the windows. Heather has been murdered within the car by the killer, who had been hiding in the backseat.
