In the summer of 2014, a World War II veteran sneaks out of his care home to attend the 70th anniversary commemoration of the D-Day landings in Normandy.
Inspired by events in A.D. 60, Boudica follows the eponymous Celtic warrior who rules the Iceni people alongside her husband Prasutagus. When he dies at the hands of Roman soldiers, Boudica’s kingdom is left without a male heir and the Romans seize her land and property. Driven to the edge of madness and determined to avenge her husband’s death, Boudica rallies the various tribes from the region and wages an epic war against the mighty Roman empire.
