During World War II, all Allied and Axis service personnel that end up in Ireland are to be interned for the duration of the conflict. Two pilots, one from the Royal Canadian Air Force, Miles Keogh, portrayed by Campbell and one from the Luftwaffe, Rudolph von Stengenbek, portrayed by Macfadyen, both fall in love with a local Irish girl, Mattie Guerin played by Butler. The relationship is further complicated by Byrne, who plays the unceasingly vigilant internment camp commander, Commandant O'Brien. (fonte: Wikipedia)
