AU from the end of series 2.
France, 1916 - During the Battle of the Somme, Thomas meets a young man named Alistair and, drawn to each other, they start an affair at the front. When Alistair is wounded and returns home to England, Thomas assumes him dead and moves on. However, Alistair—shell shocked and struggling to recover—clings to his memories of Thomas. They are reunited years later and have a chance at a new beginning together, but their partnership doesn't go unchallenged. Side by side, they must face the trials of an illicit bond and a family that doesn't approve.
