The 1960s, Netherlands. Thomas doesn’t realise it yet, but he has special powers. The nine-year-old sees things others cannot. He lives in a strict, religious family where his father, quick to cite the word of God, often resorts to violence. As a sense of injustice grows within him and a longing for freedom takes hold, Thomas begins writing his Book on Everything. In it, he wishes for his father’s punishment and encounters a host of unusual characters: Jesus Christ, a levitating lady with a piano-loving cat, tropical fish swimming in city canals, a young peg-legged witch living next door, and many others.
