Chrissa Maxwell (Sammi Hanratty) and her family move from Iowa to be closer to Chrissa's "Nana" after their grandfather died. At her new school Chrissa has a hard time making friends and is bullied by three girls who call themselves the Queen Bees. Chrissa tries to befriend Gwen Thompson (who is also bullied by the Bees) but at first Gwen avoids Chrissa. Chrissa finds out later that she avoided her because Gwen was homeless and ashamed of it. The Bees find out that Gwen is homeless and begin to make more fun of her. They get in trouble and are sent to the principal's office. Sonali, one of the Queen Bees who was tired of bullying and being bullied, apologizes to Gwen the next day about all the mean things she has done to her and leaves the Queen Bees. She then becomes friends with Chrissa and Gwen. After the incident, the bullying gets more intense. Posters and rumors are passed around about Chrissa by Tara, the Queen Bee leader, and her best friend. Chrissa quits her school swim team because she is tired of Tara being mean to her. Chrissa gets advice from her art teacher to tell her parents about the bullying. She tells her parents and they tell her that sometimes bullies are mean because they want to feel better about themselves by insulting others. Chrissa decides to rejoin the swim team for the big swim competition. She realizes that she and Tara have to work together if they want to win the relay. Although Tara is reluctant, Chrissa assures her that though they may not be friends, they can still work together to win. Their team work earns them their victory, and they reconcile and hug. The fourth grade class then does a project to make people aware that many kids are bullied and that bullying is wrong. In the end Chrissa, Sonali, and Gwen are best friends.
