November 1918.
Stanley is convinced that the precious stained-glass window from the church, that Martha’s grandfather hid during the war, will save his village, and his mother, who is desperately ill. But Martha refuses to help him search, wanting to keep her beloved grandfather’s secrets safe.

When Stanley gets ill too, Martha visits the village, and realises she must act to help. She begins her own treasure hunt, even as her father is also struggling with the aftermath of the Great War. As the people who are most important to them suffer, Martha and Stanley are desperate to restore the village's fortunes before it's too late.

Stanley believes the lucky stained-glass window in the church that Martha’s late grandfather removed during the war is the answer to curing his mother. When she becomes blind and Martha’s father’s mental health deteriorates, Martha and Stanley step up their search. Will they find the panels before it’s too late?
