"The Convict" is a story of stolen identity used to bring out truth and reconciliation.
Hanley, Saunders, Caje, and Kirby are looking for Andre Dupre, a French Resistance fighter who will take them to his boss Lambrelle to pinpoint locations for air drop of supplies to be used by the Resistance to blow up five American objectives. Dupre is killed by a German and seeing opportunity, Boulanger (excellently played by Gilbert Roland) decides to steal his identity. Upon rendezvousing with the squad, Boulanger leads them toward his escape in Switzerland as opposed to Lambrelle. Boulanger makes a huge mistake en route and Saunders picks up on his true intention. He takes Boulanger prisoner suspecting he's an escaped convict. When they run into Boulanger's son Pierre, the tide changes as Pierre agrees to take them to Lambrelle believing his father to be innocent.
Screen writers Kay Lenard & Jess Carneol did an excellent job in that the story is very plausible. It's almost as if they worked backwards from truth & reconciliation to the beginning identity theft. It takes real creativity to conceive a story like "The Convict." The old man on the train tells of the escaped convicts while Pierre intercedes to change direction and get the squad to their objective. And Bernard McEveety takes care of his specialty in the superb ending sequence which effectively binds the episode together.
By the way, maybe our troops should practice knife throwing. In times of war it can be extremely useful.
