Its a Horror spin-off to the reality show Big Brother.
Basically England is infected by a zombie plague that brings the dead back to life and makes them kill people (as zombies do) anyway the only survivors are the Big Brother contestants (one of which is Davina McCall, playing herself) who have no idea of the horrors outside...
...until eviction day so the contestants have to find a way to survive and work together!
This looks like it will be good, although i hate big brother,
I bet it will be similar to the movie Shaun of the Dead
