You'll meet plot-device park rangers cringing in horror, learn all about the radioactive element "atmospherium," and ultimately witness the most absurd narrative coincidences this side of Seinfeld.
But these dumb marrieds are not the only seekers of the meteorite; a pair of crash-landed aliens need to track down the atmospherium to power their ship, and an "evil scientist (?)" needs the element to resurrect a "lost skeleton" that he may "take over the world" in a poorly-defined fashion.
Anyway, the aliens briefly and naively join forces with the evil scientist to acquire the atmospherium, only to be (surprise!) betrayed by the evil scientist -- who then tries to force the female alien to marry the (now up and kicking) Lost Skeleton of Cadavra.
