Max doesn't own much, but he has a beautiful cap. He throws it high into the air – and when it lands back with him, he smells it: sometimes it smells like the street, sometimes like a soccer field or balcony flowers. Once, Max's cap lands on a bird's head and flies away with it. An incredible journey begins, a journey around the world – for real? ... or just in Max's head? Either way, the journey is turbulent and amazing. When the cap reappears right at Max's feet, it looks quite worn out. What do you think it smells like now?.
