Táto séria sleduje skupinu mladých ľudí, ktorí sa ocitnú v boji o prežitie proti hordám nemrtvých. Keď sa bežný výlet zvrtne v krvavú nočnú moru, musia hrdinovia čeliť nielen vraždiacim zombíkom, ale aj vlastným strachom a sporom. Napätie a akcia sa miešajú s prvkami hororu, zatiaľ čo postavy zisťujú, ako ďaleko sú ochotné zájsť, aby prežili v brutálnom a smrteľnom svete.
When their ski-coach pulls up at a cafe, new girl Bobby and rebel Smitty stay behind. They hardly know each other, but that changes when they see the others coming back. Something has happened to them - something bad. Soon, only a pair of double doors stands between those on the bus and their ex-friends outside.
The good news: Bobby survived her Undead school trip. Bad news: her best mate, Smitty, is missing and there are starving zombies everywhere. Somehow she must find some living friends - and an antidote - before it's too late ...
