The Fourth of July weekend at Bluewater Kingdom was supposed to break attendance records. It broke something else instead.
A massive tropical storm is hammering central Florida. The heavy rain is flooding the park and overwhelming the underground drainage system. The rising waters are pushing something ancient and ferocious out of the limestone caverns below.
A breeding colony of reptilian apex predators has lived beneath the wave pools for decades. Now the storm surge has trapped twelve thousand guests inside the park. The power is out. The submerged midways are the perfect hunting ground.
Lifeguard Danny Reeves and a small crew must navigate the dark and dangerous waterpark to lead the survivors to safety. They have to move fast before the creatures turn Florida's biggest attraction into a feeding frenzy.
