A mysterious UFO crashes near Los Angeles and unleashes an invisible alien from an unknown planet. The Phantom goes on an unwitting rampage of death and destruction as it struggles for survival in a strange new world. A group of valiant scientists race against the clock to find the creature before further disaster ensues. This remarkably serious film noir documentary-styled science-fiction epic was directed by W. Lee Wilder (Billy's brother) who was also responsible for such similarly sober "masterpieces" as The Snow Creature (1954) and Killers From Space (1954).
