Laure is a 10-year-old girl whose family moves to a new address in Paris. One day Laure sees a group of boys playing outside the window and goes to play with them, but they disappear quickly. Instead, Laure meets Lisa, a neighborhood girl. Lisa assumes that Laure is a boy and asks for her name. After a moment's thought Laure introduces herself as Mikäel. Lisa then introduces Laure as Mikäel to the rest of the neighborhood children stating that "he" is the new kid in the apartment complex. Laure becomes friends with Lisa and the boys, showing some soccer skills and managing to keep up the appearance even when they go swimming, by putting a clay penis in the swimming trunks she cut from a one-piece.
