Paris, 1963. The youngest of the siblings, Roland, is an exceptional boy. Doctors have said he will never walk, but his stubborn mother, Esther, refuses to accept this. With unwavering hope and the suppression of negative thoughts, he fights against (it would seem) inexorable fate. Her enormous charisma and love, her power of persuasion, her desire to play and her penchant for alternative medicine constitute the world in which Roland discovers the wonderful life his mother has dreamed for him.
