Sometime in 1968 a strange viral outbreak is contained within the walls of a military hospital in Pennsylvania: all those exposed are destroyed and burned to the ground. A wall of silence befalls the incidence, and soon enough only a vague myth remains. The hospital becomes a civilian mental treatment center.

Set in a mental hospital in Pennsylvania, five patients about to be released uncover a secret buried within the compound and unleash a virus (contagium) designed to force Humanity to evolve into powerful creatures capable of astounding feats…and incredible cruelty. In order for this new Human to survive it needs to feed on human flesh: but a bite from these creatures creates a new state of existence, the Creature’s subordinate, the Living Dead. It’s up to our terrified heroes to choose to accept this fate or to fight it, even if it means their own destruction.
