Death has come with fury (and a bit of dark humor) to a little town south of Chicago.

A healthy patient dies without explanation. A tour bus crashes; no survivors. Electrical fires. Strange diseases. Odd, deadly accidents. 

And only a group of teens know why this is happening.

On an ordinary weekend, out on a drive at night, four friends find . . .

A portal to hell

And they accidently release into the world, 

An army of grim reapers

Reapers with a hatred of all humankind—"shadows" that immediately embark on

A worldwide killing spree

the likes of which has not been seen since the Black Plague. Or the Purple Plague before that.

Now, only Conner, Almira, Ricky, and Flower can save the world. So the friends must

Sacrifice themselves

In order to bring order back to a broken planet, by going

Back through the portal . . .

Back into a world of screaming darkness . . .

Back to the dominion of death . . .

But hopefully back in time for dinner
