A series of bizarre occurrences suddenly plague the island of Cielo Nublado. A dead whale washes ashore riddled with enormous bite marks. A fishing charter is reported missing, jet skiers vanish, and a yacht is found mysteriously ravaged after some kind of enormous impact.

Chief of Police Nico Medrano tries to investigate the matter. His search for answers puts him on a collision course with an eighty-foot predator, long thought extinct. Violent and merciless, it has risen to the surface, and seeks to wreak havoc on the small island community.

Things only get worse for Nico after he discovers that a ruthless band of criminals, responsible for the deaths of two Miami cops, are lurking on the island. As the body count mounts, Nico is forced to simultaneously battle two separate monsters: Man and Meg.

The result is a bloodbath.
