Dan has had it with his Dad. He's not going to take the abuse anymore. He's sixteen, old enough to leave; maybe he'll find his long-lost mother in the process. What Dan doesn't count on is being followed by his younger brother Eddie, and what began as a reckless solo journey becomes one of responsibility. Their bond is tested by the characters they encounter and when they fall in with a small group of would-be soldiers marching over the mountains to join the fight in the Great War, who take the boys under their wing, the experiences they share together with this rag-tag crew will shape all their lives forever.
