Almost eleven years after the futile and disastrous expedition on the distant moon LV-223, the deep-space colonisation vessel Covenant equipped with more than 2,000 colonists in cryogenic hibernation, sets a course for the remote planet Origae-6 with the intention to build a new world. Instead, a rogue transmission will entice the crew to a nearby habitable small planet which resembles The Earth. The unsuspecting members of Covenant will have to cope with biological foes, beyond human comprehension. Ultimately, what was intended as a peaceful exploratory mission, will soon turn into a desperate rescue operation deep into the cold infinite space.
