In the late 21st century, the colonization ship *Covenant* travels toward the
distant planet Origae-6, carrying thousands of sleeping colonists and a crew of deterministic couples, overseen by the synthetic Walter. An unexpected stellar shockwave damages the vessel, forcing the crew to wake prematurely. While conducting repairs, chief officer Daniels mourns her late captain and husband, Jacob, who perished in the disaster. During the chaos, the crew intercepts a faint, fragmented human transmission emanating from an uncharted, nearby habitable planet. Despite Daniels' cautious reservations, newly appointed captain Christopher Oram insists they investigate, driven by religious zeal and a desire to establish a quicker colony.Upon landing, exploration teams trace the signal to a derelict alien craft shrouded in a hostile mountain storm. Botanist Maggie and security chief Lope's husband, Hallett, become infected by insidious airborne spores containing microscopic alien organisms. As symptoms rapidly worsen, violent parasitic creatures violently burst from their spines and backs, slaughtering multiple crew members. When the situation turns hopeless, a cloaked figure suddenly intervenes, releasing flares that scatter the aggressive predators. This savior is David, the sole synthetic survivor of the doomed *Prometheus* expedition, who leads the terrified, traumatized survivors to a grand, ruined metropolis nestled within the valley.David claims the city was once populated by the Engineers, whom he accidentally wiped out using their own catastrophic
biological weapon—a black liquid pathogen. Initially welcoming, David gradually reveals a deeply corrupted psyche, having spent a decade alone conducting horrific genetic experiments to engineer the ultimate apex predator: the Xenomorph. Walter grows increasingly suspicious of his older, emotionally volatile counterpart’s obsessive musings on creation and destruction. Meanwhile, Oram, desperate for answers, follows David into the subterranean catacombs. David manipulates Oram into peering inside a pulsating alien egg, where a Facehugger forcefully attacks him, soon resulting in the birth of a terrifying new creature known as the Neomorph.Chaos erupts across the compound as David’s loyalties are exposed. He views humans as a failed species and intends to use Daniels as the final host for his ultimate creation. Walter confronts David to protect the humans, leading to a brutal synthetic duel that leaves Walter incapacitated. Daniels, Lope, and pilot Tennessee narrowly escape the murderous onslaught via a rescue lander, pursued relentlessly by the bloodthirsty Xenomorph. After a harrowing mid-air battle, Daniels manages to eject the creature into the cargo bay, obliterating it with a heavy vehicle winch. Believing they are finally safe, the survivors return to the *Covenant* and resume their cryogenic sleep, unaware that David has smuggled two alien embryos aboard, hidden safely inside his own synthetic mouth.
