Quelques mots d’un étranger dans le métro ont changé sa vie. La ruine menace sa famille, et il se voit désormais confronté au pire cauchemar d’un espion : l’exposition. Freddy Craven est le héros et le mentor entre les mains duquel Will Flemyng pourrait déposer sa vie, mais les circonstances vont l’amener à jouer la carte personnelle. C’est alors qu’un meurtre étrange révèle un réseau de secrets qui va mettre à mal sa loyauté envers ses proches. Tandis que les rues de Paris se couvrent de barricades, Flemyng, à l’instar de ses amis et de ses ennemis, découvrira qu’on n’exhume pas des secrets sans exposer sa propre vie.
