A motorist hits a man with his car. The man is taken to the hospital and declared dead on the spot. Moments later, without saying a word, the dead man comes back to life and leaves the hospital. Steed and Peel are called to the hospital to investigate. They talk to Whittle, the motorist, who is completely mystified by what happened but glad to know that he didn’t kill someone.
Steed and Peel's investigation leads them to a second meeting with Whittle, a fight with the undead man, a trip to the Ministry of Technology - Neotoric Research Unit (MOT-NRU), and the discovery of a plot to replace government officials with duplicates who like the one Whittle hit with his car.
