Here's a description of the show (from IFC):
Britain has been hit by an epic problem. The dead are returning to life and attacking the living. The people they kill get up and kill. And it's spreading like wildfire. Within two days, 80 percent of the population is dead. No one knows how this problem started or how widespread it has become, because there are no news channels anymore.Here's a trailer:
The entire social structure has collapsed in the space of 48 hours. Tiny groups of survivors are holed up across the country, unaware of each other, besieged inside abandoned houses, abandoned hospitals - abandoned anything. Surrounded by growing hordes of the living dead - mindless eating machines powered by raw instinct - they fight to survive, around the clock.
Few people remain who aren't worried about this living nightmare: the remaining contestants in the reality TV game show, "Big Brother." Cocooned in the safety of the Big Brother house, they're blissfully unaware of the horrific events unfolding in the outside world... until eviction night when the walking dead descend on the studio.
In a cruel reflection of the game show they were cast in, one by one they fall victim - devoured by the hungry, unthinking masses outside. Staying alive requires teamwork - a tricky job when you're a group specifically selected by TV producers to not get along and drive each other crazy.
I have to say I'm pretty excited.
