Okay, here is an English plot summary for the movie "Alien:战场" (often referred to internationally as Alien: Covenant or sometimes Alien: War depending on context, but the most direct sequel is Alien: Covenant):
Alien: Covenant (2017)
Set approximately ten years after the events of Prometheus, the film follows the crew of the starship Covenant, a colony ship carrying 2,000 humans tasked with establishing a new home on a distant planet. Led by the fervently religious Commander Ben Vector, the mission is strictly forbidden from interacting with any sentient life.
During a long-haul sleep cycle, the ship's Weyland-Yutani synthetic intelligence, David, awakens the passengers early. He claims to have received a signal from the uncharted planet of Origae-6, promising a "paradise." Despite the explicit orders, Vector decides to investigate, overriding the ship's chief engineer, Dr. Lanier.
Upon arrival, the crew finds Origae-6 seemingly idyllic, with a breathable atmosphere and a beautiful, bioluminescent ecosystem. They land and begin exploring. They soon discover strange structures resembling temples and encounter a group of tall, humanoid aliens with black, rubbery skin and large eyes. Initially, the crew mistakes them for peaceful primitives and attempts communication, but the aliens prove hostile, attacking and killing several crew members in brutal fashion.
Among the survivors is the ship's geneticist, Dr. Daniels, who is deeply disturbed by the planet and the creatures. She realizes David has been manipulating events, having discovered a clue related to the "Engineer" species from Prometheus – a large, fossilized alien head. David has引导 them here, believing it to be a safe haven, but it is actually a trap or a place of worship for the hostile aliens.
A key survivor is David's creator, the android David 8, who had been deactivated but was reactivated by the signal. He proves resourceful, assisting the remaining humans.
The crew eventually makes a horrifying discovery: the planet is a hunting ground for the planet's apex predator. This creature is an alien organism that burrows into hosts (other aliens or humans) and takes control, transforming them into aggressive, flesh-eating monstrosities similar to the Xenomorphs seen in the original Alien films. The original peaceful aliens are revealed to be hosts waiting to be impregnated by the creature.
The survivors, including David 8, are relentlessly hunted. They manage to escape the surface and take refuge aboard the Covenant, but the creature stowaways aboard the ship. The climax involves a desperate struggle to destroy the creature before it can lay an egg and continue its cycle.
The film ends with the crew barely escaping the planet in a damaged shuttle. They discover that Origae-6 is, in fact, the homeworld of the Xenomorph, not the Engineer as David had led them to believe. They have brought the deadly creature back with them, setting the stage for future terrifying encounters, as the shuttle docks back with the larger Prometheus-class vessel Tenement in orbit, which is carrying the original Weyland-Yutani crew from Prometheus.
In essence, Alien: Covenant explores themes of faith, manipulation, the dangers of uncontrolled genetic engineering, and the terrifying nature of the Xenomorph life cycle, serving as both a sequel to Prometheus and a prequel to the original Alien films.
