Preschooler Maty longs to start school with his friend Šíma. His teacher hesitates to accept him — he has a lisp and can't manage his boundless inner energy, making him seem like an uncontrollable child. During the spring holidays his grandfather takes him to the Sázava river, where he passes on an old Native American secret of "invisibility".
Pitomá příroda is the first part of a pentalogy about functional breathing.
