James Megellas, affectionately known as "Maggie," led H-Company of the 504th Parachute Infantry Regiment through some of the most horrific battles and deadliest missions of World War II, including the Battle of Anzio, Operation Market Garden and the Battle of the Bulge. MAGGIE'S WAR chronicles the evolution of a citizen into a fearless platoon leader, and the transformation of a young man into the most highly decorated officer in the history of the famed 82nd Airborne Division. Seven decades later, cameras follow Megellas, now a retired Lieutenant Colonel, on an emotional return to Europe with a small group of family, friends and 82nd Airborne veterans. Together they visit old battlefields and war memorials and encounter Dutch citizens still grateful for their sacrifice.
