In a not-so-distant future, an elite group of space marines is sent to a remote research facility on a barren moon of Mars. What starts as a mission to investigate the loss of contact with a team of scientists soon turns into a nightmare when they uncover a deadly secret hidden in the depths of the laboratory. There, the team faces horrifying creatures, the result of failed genetic experiments that have unleashed a malevolent force.
Sergeant John Grimm, a combat expert and the only one with a brother involved in the experiments, leads his men in a fight not only for their survival but for the salvation of humanity. As they navigate through the dark corridors of the complex, the team must confront their worst enemy: not only the monsters but also the secrets of the past that lead them to question reality itself.
Tension rises when the group realizes that the source of the threat may be linked to an ancient artifact found in the ruins of Mars. Desperate to escape and uncover the truth, the marines find themselves caught in a race against time, battling both the unleashed enemies and their own survival instincts. With every corner they turn, horror intensifies, testing not only their courage but also their humanity.
