1812: Matthew Hawkwood is stranded in America, behind enemy lines. Heading for the safety of the Canadian border, Hawkwood's route gives him a chance sighting of former comrade Major Douglas Lawrence – within a consignment of British prisoners. As they make their escape they uncover a plot to invade Canada. Pursued by a relentless enemy, Hawkwood and Lawrence set off across the snow-bound Adirondack Mountains; the land the Iroquois call 'The Hunting Grounds'. But they are not alone.
