Maty, a preschooler, would love to start first grade alongside his best friend Šíma. According to his teacher, however, he should stay in preschool for another year because he’s too wild, doesn’t listen to his mom, and has a lisp. Fortunately, his grandfather is a bit of a magical grandpa. He knows a Native American secret that might help his grandson. He takes Maty to his cabin far from civilization and, surrounded by nature awakening in the spring, tries to prepare him for his upcoming enrollment interview. The first moments in the wilderness aren’t easy at all for a city boy, because there’s no PlayStation or TV at the cabin.
