Many children live in a poor cottage, the oldest of whom is Ondra. The cottage can no longer support them all, so the father sends his son out into the world to learn a trade. On his journey, Ondra meets an old man, to whom he offers his last bun. The mysterious old man advises him on which path to take and also gives the boy a gift. On his journey, Ondra meets many people and proves his cleverness in each encounter. When he arrives in the city, he looks around the shops and thinks about which trade he could learn. He chooses a goldsmith. He is accepted and is so skilled that his master allows him to make jewelry for the princess, with whom Ondra falls in love. The princess is mute, but clever Ondra is sure to find a way to deal with that.
