Population Zero (2015)

Samantha and Veronica are out and about in the countryside. Samantha is looking for her brother, who is supposed to be stationed there somewhere, but hasn't checked in for a suspiciously long time. But instead of a couple of nice country bumpkins, all the two find are some ravenous zombies. The lusty local Jackson helps, and they are able to escape. Unfortunately, Samantha, does not look concentrated enough on the road and puts the car in the ditch. So they continue on foot until they find an abandoned house. Inside, soldier Snyder and the two locals George and William have already entrenched themselves.
