Welcome to the world of war veteran Zach. As the last man standing, he has retreated into a tiny dugout under a barrage of hostile fire. His enemies are cunning, using every trick in the book to mess with his mind. Even the landscape is weird: audibly, chemically and, most of all, physically... it is a cardboard box, in Zach's kitchen, in Port Talbot. His wife whispers, kindly, that it's safe to come out. But is it a trap? For if the real enemy is Zach then who will win if he loses?
