It's 1914 and Liam Mannion is forced into exile for a crime he didn't commit. He flees Balbriggan, the only home he has ever known and travels to England, where he enlists and endures the torment of trench warfare in France. Five years later he's back in England, a changed man, living in the shadow of his battlefield memories. Liam finds work in a Manchester cotton mill but prejudice and illness soon see him destitute. Starving and desperate, he enlists in a new military force heading to Ireland - the Black and Tans - and is posted to the very town he fled as a youth. While he has been away Liam's childhood friends have joined the republican cause, while his brother has allied himself to the Crown forces. Liam must wrestle with his own conflicted feelings about duty to the ruthless Tans and loyalty to his friends. The potent combination of ambition, patriotism and betrayal collide, forcing him to act as he comes face to face with the man who spread lies about him all those years before.
