Waking up after a deadly train crash in Tbilisi metro, Guga finds himself surrounded by dead people and zombie like creatures. While trying to escape the subway, he meets Elene and they continue struggle for survival together.
Guga and Elene plan to go to Tskaltubo resort, where Ana's school excursion was supposed to be held. Two people from military base offers to accompany them.
Guga, Elene and their military companions go to the cave, searching the girl. In the meanwhile the situation in the sanatorium gets tensed. Dato is hiding something very important from everyone.
Driving back to Tbilisi, they are looking for a secret tunnel, where Levan thinks they can settle for a night, but it seems that there is no safe place left any more: they encounter zombies in the cave as well.
