Her best friend, Allison, is the complete opposite. Allison isn't a very good student and gets herself in trouble the whole time. When Allison goes to the biggest party in the area, Maddy has to stay home. Allison gets wasted and can't remember anything when she wakes up next to Harry Styles. Maddy's life changes completely when she meets the womanizer named Louis.
