Is Rien ne t'efface coming back?

Ten years after the tragic death of her son Esteban, Maddi meets Tom, a young boy who looks uncannily like him. Intrigued, she moves from her native Basque Country to be closer to Tom in Auvergne. She quickly discovers that in addition to the physical resemblance, Tom has flashbacks and visions of Esteban's memories. When a series of murders rocks the peaceful region, Maddi can't help but wonder: are these events connected to her son's death? Who is Tom really, and what is his connection to Esteban?
