[1] Graveyard Shift is set in Gates Falls, a small town in Maine, and the action largely takes place in a textile mill.

A young drifter named Hall has been working at a decrepit textile mill in a small town in Maine when the cruel foreman, Warwick, recruits him and others to assist with a massive cleaning effort.

The basement of the old mill has been abandoned for decades, and over the years, a monumental infestation of rats has taken hold.

This rat empire, cut off from the rest of nature, has allowed the animals to evolve into a strange and varied combination of creatures, complete with its own bizarre, self-sustaining ecosystem.

Meanwhile, the other team of workers on the surface wonders what has happened to them and, with no idea what kind of horror awaits them, prepares to descend into the basement.
