 Honeymooning in Hungary, Joan and Peter Allison share their train compartment with Dr. Vitus Verdegast, a courtly but tragic man who is returning to the remains of the town he defended before becoming a prisoner of war for fifteen years. When their hotel-bound bus crashes in a mountain storm and Joan is injured, the travellers seek refuge in the home, built fortress-like upon the site of a bloody battlefield, of famed architect Hjalmar Poelzig. There, cat-phobic Verdegast learns his wife s fate, grieves for his lost daughter, and must play a game of chess for Allison s life.
