Moontrap

During a mission in Earth orbit, the crew of the space shuttle Camelot encounters a derelict ship containing a mummified corpse and a pod. Colonel Jason Grant retrieves the ship and its contents and brings it back to Earth. The scientists studying the artifacts make an astounding discovery. They are over 14,000 years old and came from the Moon.

The pod latches itself onto lab equipment and turns itself into a killer cyborg. Grant soon learns the pod belongs to an ancient alien race that is bent on the conquest of Earth.
