When an industrial spy steals a Xenomorph egg, former Colonial Marine Zula Hendricks must prevent an alien from killing everyone on an isolated colony planet.

Corporate spy Tamar Prather steals a Xenomorph egg from Weyland-Yutani, taking it to a lab facility run by Venture, a Weyland-Yutani competitor. Former Colonial Marine Zula Hendricks - now allied with the underground resistance - infiltrates Venture’s security team.

When a human test subject is impregnated, the result is a Xenomorph that, unless it’s stopped, will kill every human being on the planet.
