Retired Major, Shaun Turner, returns home from an annual meetup for veterans of the Iraq War. Upon reaching his small rural hometown, it becomes clear to Shaun that, in the few short days he was absent, something awful has happened. There are no longer any people left in the town. Instead, the otherwise deserted streets are populated only by grotesque monsters bearing a vague resemblance to the neighbours who, just days ago, saw Shaun off with a smile. Shaun’s plan is clear: get home as quickly as possible, save his wife and daughter and escape from the hellscape he once called home. But Shaun soon comes to understand that that won’t be as simple as it sounds and that the evil with which he now has to contend is even more horrifying than the battles he fought in many years ago.
