White as Snow (Captain Scarlet and the Mysterons)

"White as Snow" is the eighth episode of Captain Scarlet and the Mysterons, a British Supermarionation television series created by Gerry and Sylvia Anderson and filmed by their production company Century 21 Productions. Written by Peter Curran and David Williams and directed by Robert Lynn, it was first broadcast on 3 November 1967 on ATV Midlands.

Set in 2068, the series depicts a "war of nerves" between Earth and the Mysterons: a hostile race of Martians with the power to create functioning copies of destroyed people or objects and use them to carry out acts of aggression against humanity. Earth is defended by a military organisation called Spectrum, whose top agent, Captain Scarlet, was murdered by the Mysterons and replaced by a reconstruction that later broke free of their control. Scarlet's double has a self-healing power that enables him to recover from injuries that would be fatal to anyone else, making him Spectrum's best asset in its fight against the Mysterons.

In "White as Snow", the Mysterons, announcing that they intend to assassinate Colonel White, almost succeed in crashing a reconstructed space satellite into Cloudbase. They make another attempt on White's life when he goes into hiding on board a navy submarine.
