Synopsis by Hal Erickson
Powerful but gullible German industrialist Otto Kelmann (Wilfred Hyde-White) is on the verge of handing over his munitions empire to a "new Hitler" named Colonel Marcus Von Frank (Hans Gudegast), aka Eric Braeden). It is up to the IMF to smash Marcus' movement by forcing Kelmann to realign his thinking. This is the episode in which IMF agent Rollin Hand convincingly poses as the real Adolf Hitler. Written by Mann Rubin, the man responsible for the thematically similar first-season Mission: Impossible episode "The Legend", "Echo of Yesterday" first aired on December 10, 1967.
