James Ryker and his protégé, Henrik Svenson, travel to the small alpine town of St Vincent, recently rocked by the triple murder of a prominent family. The sole survivor of the horrific crime, teenager Sophie Thibaud, has since been cared for by her aunt. Upon their arrival, however, Ryker and Svenson discover that Sophie is now missing too, and it’s not long before Ryker uncovers evidence of a wider conspiracy at play.

Their search for Sophie and the truth takes them to Lyon and beyond, crossing paths with ruthless mobsters and corrupt police on the way as Ryker looks to expose those involved in enriching themselves through any means possible. But in searching for answers against all odds, can Ryker remain protector to those who need him most?
