Kim has had enough: of school, of her girlfriend, and even more so of her mother. Because of her, Kim's father is now gone. Just gone. So Kim decides to leave. She can't go back, only forward. Until she finally arrives at the one place where she can still be.
The Lindenhof School is expecting a busload of proper young English ladies as exchange students. The shock is great when the students turn out to be teenage boys! But while Mademoiselle Bertoux is delighted to stage “Romeo and Juliet” with real boys, both Hanni and her sister Nanni fall for their “Romeo,” Clyde.
The summer break is over and the twins returned to Lindenhof. That has now changed a lot. Because Mrs Theobald had to travel, Mademoiselle Bertoux has taken the lead.
Duas irmãs gêmeas idênticas são mandadas para um colégio interno por conta de suas travessuras em casa. Enquanto a doce Nanni já faz seus primeiros amigos, a esquentada Hanni passa por mais dificuldades para se adaptar à nova rotina. Quando um importante jogo de hockey está para acontecer, as gêmeas precisam se unir e tomar uma decisão que pode salvar toda a escola.
