Freddie Watson is a stilted young man who has not gotten over older brother George's disappearance on the Western Front during WWI. It is now 10 years since the Armistice, and Freddie, after a stay in a mental institution, has come to the French Pyrenees to find peace. While motoring through a snowstorm, he crashes his car and ends up in the small village of Nulle, where he meets a beautiful young woman named Fabrissa. In the course of an evening, Fabrissa tells Freddie a story of persecution, resistance, and death, hinting at a long-buried secret. By the next morning, she is gone, leaving Freddie alone to unlock a ghostly mystery hidden for 600 years.
