Moontrap 1989

On July 21, 1969, a robotic eye emerges from the lunar soil, quietly watching the Apollo 11 landing module lift off.

Two decades later, the Space Shuttle Camelot encounters a derelict spaceship in orbit around Earth. Mission commander Col. Jason Grant leaves the shuttle to inspect the craft and discovers a reddish-brown pod and a mummified human corpse, both traced back to the Moon about fourteen thousand years ago.

The unattended pod awakens and constructs a cybernetic body from lab equipment and fragments of the ancient remains. The cyborg kills a lab technician and exchanges fire with security guards before Grant destroys it with a shotgun blast to the head.

Using the last completed Apollo rocket, Grant and Ray Tanner travel to the Moon on a search-and-destroy mission. They uncover the ruins of an ancient human civilization and encounter a woman in suspended animation who identifies herself as Mera. She reveals the name of the killers — the Kaalium.

They survive a Kaalium attack and return to the Lunar Module, with Mera wearing her own spacesuit, but the module is gone. The Kaalium also shoot down the command module, leaving the astronauts stranded on the Moon. In a sequence of attacks, Tanner is killed, and Grant and Mera are captured. The Kaalium set course for Earth aboard a giant ship carrying humans.

Grant and Mera free themselves and locate the landing module, tangled in the ship’s machinery. Grant initiates the module’s self-destruct sequence before he and Mera escape through a hull breach, using the recoil of his pistol as propulsion. The ship explodes, and the two eventually appear on Earth as a couple.

Having learned English, Mera explains that she was placed in stasis to warn others about the Kaalium, and Grant reassures her that the threat has been defeated. Later, a surviving Kaalium pod is seen in a junkyard, quietly preparing to build a new body.

In a post-credits moment, Grant speaks with a NASA official about any debris that might have fallen to Earth, but the official dismisses the concern, insisting that any fragments would have burned up in the atmosphere.
