Identified is the first episode from the UFO TV series.


Peter Carlin's sister, Leila, has disappeared after contact with an alien craft. So he is especially pleased when, as a member of SHADO, he uses new equipment to intercept a UFO for the first time. The UFO crashes, and its pilot's body is rushed to hospital , but too late to save him. As soon as the alien's helmet is removed, the face's youthful features are transformed into those of an incredibly aged man, and he dies. But the alien's body holds a terrible secret, many of its organs are human. The aliens, a dying race, are in desperate need of replacement organs from healthy people. They have been finding their hopes of survival on Earth, many light years away, by raids in search of human organs to keep themselves alive. Commander Straker has to break the horrifying news to Captain Carlin - the dead alien has the transplanted heart of his sister.
