Background:
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.
The Story
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.
Although special effect heavy, the core of the story is both compelling and tragic. It’s the age-old dilemma of transcending our shortcomings and overcoming our fears in spite of what the sacrifice may entail.
Day of the Dead: Contagium is homage to the Dead trilogy, it hints at a possible origin to the Zombie phenomena in a manner that incorporates all known lore. It also covers some of the lesser known aspects of the original transformation and it imagines the last moments before the End of Humanity.
Producers note:
There will be four types of creatures, the traditional zombie type included. A third of the budget is geared towards building these Creatures, the likes of which have never been seen before.
