Publisher's Synopsis
John Hurt, Jessica Brown-Findlay and Vanessa Kirby star in this TV adaptation of Kate Mosse's Holy Grail adventure. When Dr Alice Tanner (Kirby) unearths two skeletons in a long-hidden cave while on an archaeological dig in Southern France, she sets in motion a chain of events across time and space. As her investigations proceed, Alice's attempts to protect her secret echo the actions of a 17-year-old girl from 13th-century Carcassonne, Alaïs Pelletier du Mas (Brown-Findlay), who has been given the task of protecting the secrets contained within three ancient and arcane books from the marauding hands of invaders.
