Liverpool, 1939. Lonely historian Tom Baines is at work on a study of the city's architectural past but the ominous news from Europe, together with his burgeoning friendship with Richard, a young photographer, and his beautiful wife, Bella, are proving a distraction.

When the bombings begin, Tom joins up as 'rescue man', retrieving the wounded and dying from the ruins of buildings, but the love affair he embarks on soon leads him into a very different kind of danger.
