During World War II, all Allies of World War II and Axis powers service personnel that end up in Ireland are to be interned for the duration of the conflict. Two pilots, a Canadian (portrayed by Campbell) and one of the Luftwaffe (portrayed by Macfadyen), both fall in love with a local Irish girl, played by Butler. The relationship is further complicated by Byrne, who plays the unceasingly vigilant internment camp commander.
