If someone you loved when missing, would you ever stop searching for them?

1921. The Great War is over and while many survivors have been reunited with their loved ones, Edie's husband Francis has not come home. He was declared 'missing, believed killed', but when Edie receives a mysterious photograph in the post, taken by Francis, hope flares. And so she begins to search.

Francis' brother, Harry, is also searching. Hired by grieving families to photograph gravesites, he has returned to the Western Front. He too longs for Francis to be alive, so they can forgive each other for the last conversation they ever had.

As Harry and Edit's path converge, they begin to get closer to a startling truth.
