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, All Movie Guide
