Spending long moments sitting in front of the window, he longs for freedom, dreaming of what it would be like to be tree, as his mother would always know that he's never far from home and that he's always safe. But over the course of his young life, Julien will become an involuntary witness to family dramas that will shake him to his very foundations for years to come.
