The Alien Covenant follows on the movie Prometheus.
When the colony ship, the Covenant, arrived at a remote planet, the members thought they have reached paradise.
But they soon realised that they found hell when attacked by a horrifying alien life-form on the surface.
David, the synthetic survivor of the doomed Prometheus, saved them and it only later came to light that there is more to David than meets the eye.
They soon find out that the dark secrets of the planet could cost them their lifes.
In a prologue, business magnate Peter Weyland speaks with his newly-activated synthetic, who chooses the name “David” after looking at a replica of Michelangelo’s statue of David.
Weyland tells David that one day they will search for mankind’s creator together.
David launches into an ominous statement about his unlimited lifespan as compared to his creator’s limited one, foreshadowing a turn in the hierarchy of their relationship.
In 2104 the colonization ship Covenant is bound for a remote planet, Origae-6, with two thousand colonists and a thousand human embryos aboard.
The ship is monitored by Walter, a newer synthetic physically resembling 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.
While repairing the ship, the crew picks up a radio transmission from a nearby unknown planet, dubbed by Ricks as “planet number 4”.
Against the objections of Daniels, Branson’s widow, now-Captain Oram decides to investigate.
