Wolfgang, a 9-year-old boy with an IQ of 125, is forced to live with his father, Carles, whom he has never seen, after the sudden death of his mother. He has one obsession, to run away to Paris to study at the Grimald Academy and become the best pianist in the world. But what Wolfgang doesn’t know is that the biggest challenge is right in front of him and that is to get along with his father.
