s04e20 ApocaLexx Now

An asteroid mothership appears out of the blackness of space. A metal hatch opens and a tadpole-like creature shoots out and heads for the Lexx. Stan awakens from a nightmare in which he was eaten by Lyekka and discovers that the alien mothership is hovering outside of the Lexx. Before he can finish telling Xev and Kai what he has discovered, an alien who has assumed the physical appearance of Lyekka from Stan's dream appears on the Lexx. She explains that she is a plant and that her species needs to consume the living matter on earth in order to survive. The Lexx crew feel that this mass annihilation is not morally correct, but they understand that the aliens do have natural survival instincts. They suggest that "Lyekka" meet with the world's leaders (specifically President Priest) in order to find some logical solution. They take a moth to Vietnam where Priest, accompanied by Bunny, is to deliver a speech at the Khe Sanh Kuntry Klub. While there, he has also arranged to play a round of golf with Pope G. Rota who will be in attendance. When the Lexx crew land in a moth, they stumble upon a decrepit building that serves as a storage room for golf equipment. Under the floor, they discover a group of American POWs who have been in hiding since the Vietnam War. They join the Lexx crew and Lyekka in the search for President Priest. When they find Priest on the fairway giving a speech, the POWs open fire with their automatic weapons. Vietnamese caddies and a group of Monks guarding the Pope return fire. A battle ensues as Hueys swoop over the golf course firing their deadly weapons at the POWs. The moth is destroyed and Stan and Priest are kidnapped during the battle by Pope G. Rota. Pope tortures them as she explains her thirst for political power. Xev, Kai and Lyekka journey upriver and rescue Stan and Priest in the nick of time. Priest agrees to let Lyekka eat Japan if she promises to leave the rest of the planet untouched. For a snack, Lyekka devours Pope. The Lexx crew leave Vietnam by joining Priest and Bunny on Air Force One. Priest promises them a space shuttle so they can return to the Lexx. Priest exorcises his bad Vietnam experiences by nuking the country.
