Baptiste is twenty-eight years old, twenty-five of whom have passed in apnea, in an unknown suffering. Suddenly memories of rape resurfaced. He was 4 years old when his lifeguard stole his childhood in a municipal swimming pool. Rather than ignore and survive, Baptiste decides to face and live. Then begins an intimate quest, in the depths of her vulnerability, to piece together her hidden past and extricate herself from this nightmare. She will lead him, three years later, on the track of the aggressor.
