Leo is a boy full of ideas who finds himself a prisoner in Pesant-Pays, a frozen kingdom where everything is heavy and silent. There, no one laughs, plays or dreams.
Guided by his curiosity and ingenuity, Leo defies the rules imposed by the magician-king and gives the inhabitants back their desire for lightness.
And what if, like him, all you had to do was imagine and have fun, and you'd never be locked in?
