A  man wakes in a field in a country he does not know. Injured and with only flashes of memory coming back to him, he pulls himself to his feet and starts to walk, setting out on an extraordinary journey in search of his home, his past and himself. His name is Owen. A war he has only a vague recollection of joining is in its dying days, and as he tries to get back to England, he becomes caught up in the flood of rootless people pouring through Europe. Among them is a teenage boy, and together they form an unlikely alliance as they cross battle-worn Germany. No one is as he remembers, not even himself. How can he truly return home when he hardly recalls what home is?
