Specialists collect in a top-secret facility to research a collection of unusual deaths on seashores alongside the Atlantic Ocean. One of many crew's scientists examines video proof to uncover a potential parasitic rationalization for the fatalities. However when a decided detective sends her the crazed writings of a mysterious homeless man, the scientist slowly learns that the precise risk could also be extra harmful -- and much older -- than anybody ever imagined. Can she persuade her colleagues of the true hazard earlier than an historical power rises from the ocean to convey insanity and demise to all of humanity?
