World War II historians Al Murray and James Holland are in Les Mésières near Utah Beach, retracing the incredible D-Day action of Staff Sergeant Harrison Summers of the 502nd Parachute Infantry Regiment, 101st Airborne. In a feat easily equal to those of the more famous 'Band of Brothers', Sgt Summers won an Distinguished Service Cross for eliminating a German gun garrison in an almost single-handed display of courage. James and Al walk through Les Mésières looking for the 'WXYZ' complex that was Sgt. Summers's objective and compare the buildings and fields to the post-action reports. They quickly realise that the standard description of how the action unfolded is flawed and put forward an alternative path taken by the heroic Summers on the morning of June 6th 1944.
