Searching for the crystal, Conan, a young courageous and never feared warrior, who does his best to save the world from the evils, goes in a long mission with his friends, but as he has to rescue the princess from the corrupted queen, everything goes out of his hands. With his cunning, he manages to find the crystal.
What happens when you take everything that makes Conan the Barbarian memorable, and strip it down to a light-hearted, PG-rated version of itself... stupid and boring and generally unintelligible.
There's a goofy MST-3K quality about Conan the Destroyer that aims for family friendly but tries to be sexy as well, something we saw a lot of in the 80s.
