In a not-so-distant future, humanity faces an apocalyptic crisis when a deadly virus, brought on by a solar storm, begins to annihilate the population. A small band of survivors gathers in a military submarine, where their personal differences, ideologies, and thirst for power threaten to make their situation as dangerous as the threat they face outside.
The protagonists, a diverse group that includes a cunning captain, a scientist clinging to the hope of finding a cure, and a warrior hardened by tragedy, must confront not only the virus but also their own despair. As time progresses, tensions within the submarine escalate, and critical decisions turn into moral dilemmas. Paranoia spreads quickly, and with each passing day, resources dwindle and loyalty becomes a luxury.
As the struggle for survival intensifies, the group discovers that the virus not only attacks humans but also has the ability to manipulate their surroundings, turning living beings into mutant creatures. With each descent into the depths of the ocean, the line between humanity and monstrosity blurs, unleashing a series of supernatural events that will push them to their limits. In this context, they question whether humanity has a future or if it has already lost its essence on the path to salvation.
