Set between the events of
Prometheus (2012), and
Alien: Covenant (2017), "The Crossing" chronicles the symbiosis of Dr Elizabeth Shaw and David, the state-of-the-art android. To escape from the rocky exomoon, LV-223, Shaw repairs David to help her pilot the abandoned Engineer Juggernaut spacecraft, in search of answers to humankind's existential questions. Will they ever find the uncharted Planet-4, the homeworld of the superior extraterrestrial race of the Engineers?
