A shark bite spreads a virus across the globe, turning the world upside down. Deep below the ocean, a group of researchers race against time to find a cure. Something has infected the lab technicians and it’s a race against time to reach the surface with an antidote before they are all killed by themselves and the sharks lurking inside the test pool and outside in the ocean.

Burned alive in an accident and locked away, the urban legend of Crispy refuses to die. Escaping the asylum, the scarred killer returns to Camp Hollow, where a group of unsuspecting campers find their weekend of fun twisted into a nightmare of fire, blood, and vengeance as his rage consumes the woods once more.
