When Martin Kemp joins the English army in order to avoid the hangman, he may just be delaying the inevitable. While he remains hopeful that at least there's the chance for some heroics, the reality is very different. Kemp's war is instead a terrifying odyssey through the panic and confusion of his first battle, the brutal realities of siege warfare, and eventually to the field of Crécy, where he faces the armoured might of the French nobility. But as an elite longbowman, when it comes to winning or losing, he could have a vital - though dangerous - part to play.
