2 - 9: Vendetta

Erskine's search for a communist spy involves him with a revenge-bent Israeli agent. For eight years, Otto Mann has stalked Karl Schindler, a Red agent and a master of disguises. When the trail leads the U.S., Mann teams with Erskine, but he hides the real reason for his search: Ex-Nazi Schindler sent Mann's wife to the gas chambers.
