Aboard the hijacked colony spacecraft, USCSS Covenant, after the disastrous
Prometheus (2012) expedition, the rogue synthetic, David, sends a transmission to the Weyland-Yutani Corporation on Earth, explaining his scientific discoveries after finding the Engineers' homeworld, the strange Planet-4. This transmission explains David's decade of experimentation on Dr Elizabeth Shaw and the destructive black-liquid mutagen, in his quest to continue Sir Peter Weyland's ambitious vision after the events of
Alien: Covenant (2017), and the creation of the perfect organism.
