It is July 1916, and as the Battle of the Somme rages, Mametz Wood echoes to the sounds of war as the 38th Welsh Regiment face the ferocity of the German army. Inspired by a true story. Dan and Billy, two young soldiers, forge a friendship in the heat of the build up to the infamous battle. When Billy is killed in Mametz Wood, he leaves behind a devastated friend and, back home, a heart-broken and pregnant wife. Altered by his experiences on the Western Front, Dan returns home to step into his friend's shoes, ultimately marrying Billy's widow and raising their baby son as his own. Fifty years later, in a clearing in the wood, Dan has returned to lay a ghost to rest. A tale of friendship, love and sacrifice set against the backdrop of world in flames.
