This 90-minute film was edited together from a number of episodes of the 1966 television series, Blue Light
David March (Robert Goulet) is an American Nazi who has renounced his country and taken German citizenship. He is ruthless and ambitious and, during World War II, is established as a Nazi propaganda expert becoming a confidant of the top German hierarchy.
But one man, a Gestapo agent called Elm (Werner Peters), does not trust David. Elm has tracked down all but one of an Allied spy ring – and he suspects that March is the unknown top man on his list.
