Dr. Alex never thought that zombies are for real. Hence, she didn't expect that in a span of a day. All hell will break loose and wakes up to find no one. Except her and a baby. Wala syang plano kung ano ang gagawin nya. Ang tanging alam nya lang ay kailangan nilang dalawa makaligtas at makaalis sa ospital na iyon na puno nang zombies.
