Faced with the prospect of joining the AEF in the "big push" against the Germans, Captain Edmund Blackadder (Rowan Atkinson) goes insane -- or at least he pretends to. Only a last-minute phone call to Field Marshall Douglas Haig (Geoffrey Palmer) stands between Edmund and the Kaiser's guns. Will our "hero" be sacrificed to the Great Cause, or will there somehow be a fifth season of Blackadder episodes? "Plan F: Goodbyeee" was originally telecast on November 2, 1989. ~ Hal Erickson, Rovi
