limited words challenge

Script Frenzy came up with the following challenge:

Let's try this: generate a random number between 1 and 100 (http://www.random.org/) and then write a pitch for a movie using only that many words.

In 57 words, here is my movie:

They are always hunting. They listen for the smallest sound to escape your lips. They are drawn to light. You have two choices. You can return to the surface where the battle still rages on, or you can learn to live silently in the dark tunnels beneath the city. Underground they listen. Can you survive the darkness?
