Lola (Miley Cyrus) leads an ordinary life, with her boyfriend Chad (George Finn), and best friends Emily (Ashley Hinshaw), Janice (Lina Esco) and Kyle (Douglas Booth). When they return to school, after summer vacation, Lola discovers that Chad has cheated on her over the summer, so the two of them break up. Lola and Kyle begin to realize that they have feelings for each other and pursue a relationship, but this is difficult due to the fact that Chad and Kyle are best friends, and Lola's "enemy" Ashley (Ashley Greene) likes to flirt with a lot of guys at school and has a crush on Kyle. Kyle and his band "No Shampoo"—including Chad—want to compete in the battle of the bands, but Kyle's father doesn't support his passion for music and feels that it is getting in the way of his schoolwork. The situation is further complicated by Chad's jealousy towards Lola and Kyle’s new relationship.
