When a wealthy man with an incurable brain tumor spends millions to have himself frozen in cryogenic stasis until a cure can be found, he gets more than he bargained for. Unbeknownst to him, sixteen years into his cryo-sleep the cryogenics company "Eternal Slumber" secretly decides to substitute a vital chemical used in the freezing process with a cheap and untested alternative to lower the company's overhead. This decision ends up killing the first patient they test it on, only to have her dead corpse reanimate and become a flesh hungry monster. When the lab is overcome with a spread of infection that is killing people and bringing them back as crazed cannibals, the staff is killed and the lab is left to ruin. Three months later the cryo system fails and our hero is rudely awakened prematurely into a world that has been plagued by a holocaust of the living dead.
