During the Cold War, amid an unprecedented arms and space race, the Soviet Union carried out secret experiments aimed at developing unusual biological weapons. According to recently declassified documents—or perhaps more accurately, persistent rumors—one of these projects involved the creation of genetically modified sharks, engineered to be virtually indestructible. The most astonishing part isn’t their existence, but their destination: these predators were sent to none other than the Moon.
Decades later, in the present day, a mission of American astronauts is dispatched to the natural satellite for research and exploration purposes. What begins as a routine scientific expedition quickly turns into an unprecedented space nightmare. Amid the lunar craters and the ruins of old Soviet installations, the crew begins to uncover disturbing signs that they are not alone. What follows is a desperate struggle for survival against a threat that defies all logic: killer sharks capable of surviving in the vacuum of space, adapted to hunt even under impossible conditions.
These sharks—products of extreme genetic engineering and the most radical strategic thinking of the Soviet era—not only retain their natural ferocity, but have evolved in an environment where no one believed life could exist. Without water, without oxygen, without an atmosphere to sustain them, their very existence rewrites the rules of biology as we know it. The question is no longer how they got there, but how to stop them.
