In the pristine landscape of Serenity Canyon Country Club, situated in the majestic red rocks just outside of Sedona, Arizona, there is little leniency for anything grotesque. The staff ensures constant tranquility, their priorities glued to maintaining this slice of paradise on Earth in their gated community with private pools, a golf course and a members-only club.

But when member Dr. Reinart becomes obsessed with his newest experimentations however, this facade begins to crumble. He unknowingly carries a parasitic virus into the neighborhood and his wife unleashes it when she decides to end their marriage swiftly and violently.

Chaos envelopes the community as the virus spreads throughout. Once high-class ruling members of society shift into bumbling monsters covered in bile and decaying flesh. Their only salvation? The lowly janitors they dedicated their living days to belittling.
