On a searing hot day in 1919, a young Russian soldier shoots another in self-defence. As the other man lies dying, the young soldier takes his horse and rides away. Years later, as a grown man in Paris whose life is still haunted by the murder he committed all that time ago, he comes across a story by a writer calling himself 'Alexander Wolf', which recounts in astonishing detail the events of that day in 1919 from the dying victim's point of view. As he attempts to find the elusive writer, the narrator becomes involved in a series of strange encounters that lead him to question life, death and his own identity.
