Devil's Tower

In the first days of the zombie apocalypse, an army physician and small team of survivors must gather their wits, their weapons and their available resources to make a last stand.

It's a sheer stone tower standing alone over a remote frontier, as iconic as it is forbidding. It is also the location of humanity's last stand. Can zombies climb?
