1918: A soldier is arrested in Durham Cathedral in the last week of the First World War, but he has no memory of who he is or how he came to be there.

He is given the name Adam and transferred to a rehabilitation institution in the Lake District where Doctor James Haworth is determined to uncover his identity. But, unwilling to relive the trauma of war, Adam has locked his memory away, seemingly for good.

Then a newspaper publishes a feature about Adam, and three women come forward, each claiming that he is someone she lost in the war. But without memory, how do you know who to believe?
