Manu and her best friend, Josefina, live at a magical school for girls, and Manu is always getting into trouble. The headmistress believes that Manu has the potential to help people with her magic, but Manu would rather have fun than fall in line. One day, a prank goes seriously wrong, and Josefina gets angry and wishes for Manu’s magic to disappear… and it does. Manu uses a dangerous spell to restore it, but it makes her magic too powerful and nearly impossible to control. Great power comes at a cost, and it may be a price that Manu isn’t able to pay!
