Superdeep begins with a daring scientific expedition in the Russian Arctic, focusing on a group of researchers exploring the Superdeep, a mysterious and seemingly bottomless underground borehole. The hole is an ambitious scientific project aimed at uncovering the mysteries of the Earth’s crust, but the deeper the team ventures, the more horrifying their discoveries become.
Led by the determined scientist Anya (Milena Radulovic), the expedition soon uncovers an ancient biological organism buried within the depths of the earth. This organism exhibits a horrifying ability to mutate and consume human life, leading the team to grapple with the question of how far they’re willing to go to survive and to uncover the truth.

As the group struggles to survive, isolation, fear, and paranoia mount. The team members face extreme physical and psychological challenges as they attempt to escape the depths of the borehole while evading the relentless, biological threat. Their journey becomes a battle of endurance, willpower, and sheer survival against an unknowable and merciless force.
