ZOMBIE: Lockdown

Prisons are supposed to keep the people on the outside safe.

When the dead walk, the very structures that protect society may become fortresses that protect those on the inside from the rest of the world...

But...

Can there really be any safe place when the dead seek to devour the living? And what happens when there is nobody left to turn the key? Will a slow, agonizing death from starvation be preferable to taking one's chances with the undead?

There may be no place left to run after ZOMBIE: Lockdown.
