Kim, Momo and Bella are three friends whose lives have so far been tough. They are bullied at school, their teachers' approach helps nothing, and it's only their strong friendship and mutual support that give them a sense of security. They choose a greenhouse as their refuge, and find there a curious seed which grows into a mysterious plant overnight. Excited by its sweet scent, they decide to taste its berries, not knowing that the magical plant can change them into boys.

The spell, however, lasts just one night, and what seems like an amazing adventure at first, gradually creates more and more problems. What if one of the girls realizes that the flower showed her who she really is? The magical fairy-tale updates a coming-of-age story with imagination. The distinctive style of the film's imagery shows how a moment of self-realization may suddenly turn our whole lives upside down.
