The Visible Filth [signed]

When Will discovers a cell phone after a violent brawl his life descends into a nightmare.

He decides to keep the cell phone just until the owner returns and everything changes. Then the messages begin. Will's discovered something unspeakable and it's crawling slowly into the light.
