The Predator

A Predator ship crash-lands on Earth. U.S. Army Ranger sniper Quinn McKenna and his team are attacked by the Predator while on a hostage retrieval mission. Quinn incapacitates the Predator and has parts of its armor sent off by mail to prove the existence of extraterrestrial life. Government agent Will Traeger has Quinn captured and held for examination. Traeger also takes the Predator to a lab for experimentation and observation, recruiting evolutionary biologist Casey Bracket to study it, who discovers that the Predator's genetic makeup contains human DNA. The Predator awakens, breaks out of its restraints, and kills the lab workers and armed guards, but spares Bracket, the only unarmed person, before escaping.
