[edit] Opening narration

"The Bible says, "Judge not, for ye shall be judged." If we look beyond the weaknesses of those among us we call feeble, we may find surprising power buried within."

[edit] Plot

A mentally challenged boy named Howie is the last unaffected person in a small town overrun by a strange madness. Miners unearth ancient parasites, in the shape of worms, that attack the brains of their hosts. While the infected townsfolk lose all their inhibitions, Howie must save his sister Sheila, the only person who truly cares for him. Deprived of Sheila's guidance for the first time in his life, Howie struggles to evade his maddened neighbors and destroy the parasites. In the process, he becomes a hero to the whole town.

[edit] Closing narration

"Mankind puts the strong, the athletic, the genius, on a pedestal. If we treated the less fortunate among us as equals we would see that they can also become heroes."
