FBI agent Madison (Neil Hamilton) goes undercover as an aviation magnate to investigate a possible spy ring. But when the baddies dispatch a vampy operative (Doris Day, not the actress who often co-starred with Rock Hudson) to seduce Madison, love gets in the way. This wartime crime thriller from ultraprolific director William "One-Shot" Beaudine also stars Victor Varconi and Charles C. Wilson as the villains Dr. Kaskell and Bruce Lane.
