At seventeen, girls are all about looking good, dressing right and making out with the cutest boys. Or they’re like Luka, who’s an ace in boxing and couldn’t care less about her looks or her appeal to boys. When she breaks a schoolmate’s nose, her parents send her off to boarding school to acquire some ladylike manners. There she’s mistaken for Frankie, a boy who hasn’t shown up, and takes on his identity. With her boxing skills, she instantly wins over her three roommates Chico, Toby and Jo, and strikes up a particularly close friendship with Chico. Her uncompromising honesty and loyalty to her new friends, however, soon get her into trouble with the headmistress and her nephew, the school bully.
