The film is a retelling the story of actor Francis Perrin and his autistic child. Séverine and Christophe are young loving parents. Very quickly, they must recognize that in their son Tom, contrary to the falsely soothing words of pediatricians and doctors of all stripes, something is wrong ... It will take three years before a diagnosis of autism falls.
