Pack your bags - this week, we're joining Steve Mitchell on another Dangerous Assignment. Brian Donlevy stars as Mitchell, the two-fisted spy dispatched all around the world on thrilling adventures and top secret missions. In this pair of international mysteries, Steve Mitchell is on the trail of a pair of missing scientists (in an episode originally aired on NBC on April 24, 1950); and he heads down south to find a stolen Civil War map (in an episode originally aired on NBC on December 16, 1950).
