But when security officer Miles Teller begins noticing memory gaps, cognitive delays, and unsettling inconsistencies among those who return, he uncovers a hidden planetary AI buried beneath the colony. As he investigates the true nature of humanity's immortality, Miles must confront a disturbing possibility: the people brought back from death may not be the originals at all, but flawless copies created by a machine no one truly understands.
