General Savage gets a sharp new navigator for the Picadilly Lily, Lt. Kurt Muller, but he starts out a bit cool to his crew-mates' efforts to welcome him into the fraternity. They soon learn why when, quite accidentally, they discover that his father was a member of the American Nazi Party prior to the war. Even Savage is disturbed by this revelation, but he's willing to live with it because of Muller's proficiency. Things get much worse, though, when Muller makes a navigational error that ruins a mission and costs the life of the bombardier. And the situation threatens to explode when it is further revealed that Muller might have been able to save the man's life. (thetvdb.com)
