The psychoanalyst welcomes Robin, son of Léonora and Damien (Clémence Poésy and Pio Marmaï), former patients he received as part of couples therapy. Aged eleven, the boy seems unaware of what brings him to the couch, and dreams of an "invisibility cloak". He refuses to spend time at his father's house for fear of Covid. Dayan ingeniously works to uncover the unspoken family secrets that weigh on his young patient, whose liveliness and sensitivity he discovers.
