The Outer Limits: 1x31
The Chameleon
Soldiers investigating the crash of a UFO are massacred. An assassin, Louis Mace, is transformed into an alien so that he can infiltrate and kill the aliens. He finds out that the aliens are peaceful and only acted in self-defense when they killed the aliens. He then helps the remaining crewman repair his ship and leaves with him.
