In 2104, 11 years after the incident on LV-223, the colonization-ship, Covenant is bound for a remote planet, Origae-6, with two-thousand colonists and over a thousand, human embryos aboard. 


The ship is monitored by Walter, a newer synthetic that physically resembles the earlier David model, albeit with some modifications. A stellar neutrino burst damages the ship, killing some of the colonists. Walter orders the ship's computer to wake the crew from stasis, but the ship's captain, Jake Branson, dies when his stasis pod malfunctions, burning him while he's still asleep. While repairing the ship, the crew picks up a radio transmission from a nearby, unknown planet, dubbed by navigator Ricks as "planet number four".[9] Against the objections of Daniels (Branson's widow), the new captain, Oram, decides to investigate.As the Covenant remains in orbit, an expedition team descends to the earth-like planet's surface and tracks the transmission's signal to a crashed alien ship. While on the surface, security-team members Ledward and Hallett divert from the main group to perform field research. Ledward steps away and accidentally steps on alien spores and is soon infected. Meanwhile, Daniels and members of the main group notice cultivated common wheat, but also the complete lack of wildlife or animal sounds. Karine helps the rapidly-sickening Ledward back to the lander where Maggie quarantines them both inside the med-bay. A small, pale, alien creature (neomorph) bursts from Ledward's back, killing him, and then mauls Karine to death. Maggie attempts to shoot the creature, but accidentally triggers an explosion which kills her and destroys the lander. The neomorph escapes to the planet's surface while another such creature bursts from Hallett's throat, killing him.The neomorphs attack the remaining crew members and kill Ankor. The crew manage to kill one before David, who survived the Prometheus mission, scares away the other and leads the crew to a city full of humanoid (Engineer) corpses. David tells them that upon his and Dr. Elizabeth Shaw's arrival at the planet, their ship accidentally released a black liquid bio-weapon which killed the native population and that Shaw died when the ship crashed in the ensuing chaos.After the crew members tell David of their mission, they attempt to radio the Covenant for help, but the surviving neomorph infiltrates the city and finds security-team member Rosenthal alone before decapitating her. David tries to communicate with the creature, but is horrified when Oram kills it. Under Oram's gunpoint, David reveals that the aliens are a result of his experimenting with the black liquid as a catalyst to create a new species. He leads Oram to an incubation chamber and tricks him into being rendered unconscious by an alien parasite (facehugger). Some time later, another alien creature erupts from Oram's chest, killing him.As the others search for Oram and Rosenthal, Walter, who has found Shaw's dissected corpse, confronts David after realizing that David had deliberately depopulated the planet when he unleashed the black liquid upon the Engineers. David explains that he believes humans are a dying species and should not be allowed to colonize the galaxy. When Walter disagrees, David disables him and confronts Daniels, telling her he will do to her "exactly what he did" to Shaw. Walter reactivates himself and fights David, allowing Daniels to escape while Lope is attacked by a facehugger. Security member Cole saves Lope, but the now mature xenomorph attacks them and kills Cole. Tennessee arrives in another lander to extract Daniels, Lope, and the victorious Walter. They kill the xenomorph before docking with the Covenant. However, Lope had been implanted with another xenomorph embryo, which bursts from his chest and kills him before escaping into the ship, quickly maturing before killing crew members Ricks and his wife Upworth. Walter helps Tennessee and Daniels lure the creature into the Covenant's terraforming bay and flush it into space.The Covenant resumes its trip to Origae-6, and the surviving crew re-enters stasis. Walter helps put Daniels under and she realizes, too late, that he is actually David. A horrified Daniels is unable to escape her stasis pod as she falls asleep while David watches. Now in control of both the ship and its population, David regurgitates two facehugger embryos and places them in cold storage alongside the human embryos before exploring the cargo bay containing the colonists in stasis. He then poses as Walter to record a log explaining that all crew members except Daniels and Tennessee were killed by the neutrino blast at the beginning of the film and the ship is still on course for Origae-6 before signing off.




For more details on individual characters, see List of Alien characters.Waterston received positive reviews for her Ripley-like role as Daniels. 

  • Michael Fassbender as David and Walter, who are synthetic androids; David is an earlier-made android, who was formerly a crew member of the destroyed Prometheus,[10] and Walter is a newer model who assists the crew aboard the Covenant.[11] 
  • Katherine Waterston as Janet "Danny" Daniels, the chief of terraforming for the Covenant mission and the wife/widow of the ship's captain, Jacob Branson. She's the third in command after Branson and Oram.[12]Waterston said she was well aware of the comparisons that were going to be made between her and Sigourney Weaver's Ellen Ripley, but that she tried not to think about it too much while filming for fear of being intimidated.[13] 
  • Billy Crudup as Chris Oram, the Covenant's first mate and Karine's husband. Oram is a self-serious man of faith who believes their role on the Covenant is an act of destiny, and shares a "contentious" relationship with Daniels.[14] 
  • Danny McBride as Tennessee "T" Faris, the chief pilot of the Covenant and Maggie's husband.[15] 
  • Demián Bichir as Sergeant Lope, the head of the security unit aboard the Covenant and husband of Sergeant Hallett.[16] 
  • Carmen Ejogo as Karine Oram, the Covenant's biologist and Chris' wife.[14] 
  • Amy Seimetz as Maggie Faris, the lander's pilot and Tennessee's wife.[17] 
  • Callie Hernandez as Upworth, the Covenant's communication officer and Ricks' wife; she also has paramedic training. 
  • Jussie Smollett as Ricks, the Covenant's navigator and Upworth's husband.[18]

Nathaniel Dean portrays Sergeant Hallett, a member of the security unit and Lope's husband,[16] and James Franco appears briefly as the deceased Jacob "Jake" Branson, the first captain of the Covenant and husband of Daniels.[19] Alexander England, Benjamin Rigby, Tess Haubrich and Uli Latukefu all portray additional members of the security unit: Ankor, Ledward, Rosenthal and Cole, respectively.[20][21]Guy Pearce reprises his role as Peter Weyland, the trillionaire founder and CEO of Weyland Corporation (now the Weyland-Yutani Corporation) who died before the destruction of the Prometheus.[22] Noomi Rapace had played archaeologist Dr. Elizabeth Shaw as a member of the destroyed Prometheus in the prequel film, and appeared in a short promotional prologue to Covenant that was set in the period between the two movies,[23] but does not act in the final cut of the movie itself. Andrew Crawford portrays the role of a neomorph,[24] while Goran D. Kleut portrays the roles of both neomorph and xenomorph.[25]Lorelei King, who portrays the voice of the Covenant's computer "Mother", was a colleague of Helen Horton, the voice of the Nostromo's "Mother" from 1979's Alien.[26]
