In seventeenth-century France, against a backdrop of witch trials, regicide and religious frenzy, Juliette, one-time actress and rope-dancer, seeks refuge with her young daughter in the remote abbey of Saint Marie-de-la-Mer, and reinvents herself as Soeur Auguste. Until a new Abbess is appointed, bringing with her a ghost from Juliette's past, a man she has every reason to fear.
