Slumber (2015)

"There will be plenty of time to sleep once you are dead" - Benjamin Franklin. True, but what if it's the sleep that kills you? Barricaded into a military bunker two scientists find themselves living their own nightmare, an outbreak of a virus that turns everyone into remorseless, uncontrollable killers as soon as they fall asleep. Richter and Peterson, men of science, but riddled with guilt at what they have created, know the end is near, the question is who will nod off first?
