It stars Dean Chekvala and Amy Kale Peterson as a couple that survives a zombie apocalypse by hiding out in a cabin in the woods.

Mike, who keeps a running tally of the zombies that he destroys, uses a rhythmic series of knocks based on classic rock songs in order to identify himself and prove that he has not become infected.

While Mike is out on a scavenging trip, Kim receives a call on her walkie-talkie from a man identifying himself as Ranger Mark.

After an unproductive outing, Mike says that the area has become too dangerous for the meager supplies that he is able to find, and he proposes that they move to the coast, where they can live in a mansion and safely run a generator.

While he is gone, she experiences a series of nightmares and hallucinations, including hauntings by Erika and her baby, Ranger Mark's taunting her over their deaths, and paintings that seemingly come to life.
