On Emblem Island, all people know their destiny from birth. The life lines on people's palms show the course of their lives, and the colorful symbols appearing on the wrists indicate future destiny and profession. 12-year-old Tor Luna, the son of the ruler of the city, was born with the leader's emblem. This means that in the future he will inherit power over the city. But Thor hates his fate. Every morning before school, where he is taught the skills of a future leader, he goes into the sea and swims for hours, dreaming of a swimmer's emblem that will allow him to breathe underwater. On the night of wish fulfillment, when the city's residents throw notes with wishes for the coming year into the fire, Thor asks the deity of wishes to rid him of the leader's emblem and give him in return the long-awaited ability of scuba diving. The next morning, Thor wakes up and sees that his leader emblem has disappeared, but instead of it, an image of a crying eye has appeared on his skin - a symbol of the curse that crossed out the line of his life. He has only a week to find the Night Witch who can lift the curse and save his life.
