A colony ship, bound for a remote planet on the far side of the galaxy, carries thousands of people asleep in cryosleep and a large cache of embryos, with the intent to establish a new human settlement. After a tragic accident during its voyage, which results in casualties including the ship's captain, the crew is awakened prematurely. They intercept a mysterious transmission, seemingly human, from an uncharted nearby planet which appears even more suitable for colonization than their original destination. The acting captain, despite some opposition from his crew, decides to investigate this new world, believing it to be an unexpected chance to ensure the success of their mission.

Upon arrival, the exploratory team, with an upgraded android amongst them, discovers an environment that seems eerily perfect for human life. While exploring, they come across the wreckage of an alien spacecraft and the remnants of a more advanced civilization. While the planet initially appears to be a paradise, the team soon encounters unforeseen and terrifying threats. The biological horrors they discover hint at a darker and more sinister reality tied to the origins of humanity and the alien species they have encountered before. The crew's hope for a fresh start progressively morphs into a desperate struggle for survival against the emerging otherworldly menaces.
