After years of traveling, Anyas parents have decided to return from Australia to their native France, and she has to attend a public school for the first time in her life. But normal everyday school life quickly causes problems for the girl. On the first day, she gets a shot with a soccer ball on the head. When no one wants to apologize for this, a violent argument immediately ensues. So she messed it up with the locals right from the start. Anya becomes an outsider, which doesn't even really bother her. But Zoé, Nils and Jade, who are also a bit different, take care of her. A new clique is formed. But the pretty outsider would prefer to be friends with Nathan, the school director's son. But he gives her the cold shoulder because it wouldn't be cool to be interested in girls in front of his buddies. Meanwhile, the girls hatch a plan to win their place in the schoolyard. A real fight ensues between the students. Now it's girls against boys. But how far can a dispute between children go?
