It's been a while since Jed Sanderson has been on a date. Naturally, the world ends the moment he finally gets one.
A violent infection spreads across the globe, turning people feral and bloodthirsty. Jed escapes to his isolated mountain farm with a small group of survivors, where they prepare for the inevitable arrival of the infected hordes. Unfortunately, the infected aren't the only threat. Nate, Jed's mentally ill brother, insists the farmhouse is haunted. As his medication supply runs low and strange things begin happening around the property, the group starts to wonder if his ramblings might actually be true. Armed with improvised weapons, questionable judgment, and an alarming quantity of narcotics, the survivors soon find themselves trapped between the infected outside, something unnatural inside the farmhouse, and a violent cult hunting one of their own.
