The year is 1401, Owain Glyndŵr and his growing forces are still no more than a thorn in the side of the English crown. But when a force of some forty men succeed in taking the prestigious castle of Conwy from under the nose of King Henry IV, it marks a dramatic shift in the fortunes of Glyndŵr's great Welsh rebellion. We follow a cast of vivid characters – from Rhys ap Tudur on the Welsh side to Hotspur on the English – as they dream of securing glory for their masters.
