Alien has Ripley and the crew of the spaceship Nostromo set down on a desolate planet on company's orders to investigate a signal of unknown origin. There they find a derelict spacecraft and a life form that gestates inside a human host which they bring aboard the Nostromo against quarantine regulations. All seems well but at a meal before entering their stases the creature emerges and escapes their detectors, after growing into an adult the alien sets about killing the rest of the crew.
