Captain Scarlet and the Mysterons S01E08 - Operation Time

General J.F. Tiempo, the Commander of the Western Regional World Defence Government, is submitted as the Mysterons' next punishment target, and the doctor who will perform a major and much-required operation on Tiempo is eradicated during a dramatic car crash involving Captain Black, and reconstructed by the Mysterons.
Spectrum are still befuddled on how the force have declared their act of retaliation as to "kill time", but Captain Magenta eventually cracks the dilemma and an elaborate game is underway by the Spectrum personnel, in order to trap the person who will take the life of the General, but the Spectrum officers discover two Msyteron secrets, which will undoubtedly assist them immensely in their continuing battle with the Mysterons.
But what they don't realise is that the doctor who will perform the neurosurgery operation on the General is a Mysteron killer.
