The documentary Knight of the Sky is presented through the eyes and words of Nicholas Dimancescu. He journeys back to Romania both to discover his own roots and to also uncover the stories of American and Romanian airmen who raided and defended Romania’s Ploesti oil refineries during World War II. The experiences of wartime ‘aces’ on both sides are recounted. Two of them, once enemies who attacked one another over Romania, meet for the first time 66 years later.
