A full synopsis of the drama shares: "The gripping true story of a young man’s journey from hero to alleged war criminal, the determined lawyer on his tail, and their search for truth in the fog of war.
"The two men go head to head in a legal and moral conflict that takes us from the battlefield - at so-called Checkpoint Danny Boy - to the courtroom, and one of Britain’s biggest ever public inquiries, the Al-Sweady Inquiry.
"Memory, evidence and trauma collide, as Brian finds himself caught on the fine line between war and unlawful killing. After his service in Iraq and years of legal investigation, will he ever be able to look his family in the eye again and be the husband, father, and son, they need him to be?
"Danny Boy is an urgent and thought-provoking drama that questions what we ask of those who fight - and kill - for their country."
