This is a fast paced episode and Matt and George are investigating suspicious deaths in a Tenctonese hospital. Matt's old school mate shows up as a Doctor there and is looking fresh and healthy, and as George notes, considerably younger than Matt, despite the fact they are the same age. They later make the horrifying discovery that Newcomers are being killed during minor operations and a body part that controls metabolism is being removed and placed in Humans and making the recipient considerably younger. This dealt with exploitation and the horrid thought of living beings being used as a commodity and was the start of a fantastic too short lived run series.
