Captain Scarlet and the Mysterons - Season 1 Episode 6 White as Snow

When a radio station relay and communications satellite is recreated by the Mysterons and its course altered towards Cloudbase, Colonel White orders the fatal missile to be destroyed before it collides with the aerial base. Infuriated at his superior for dis-regarding the non-existent, but beknown to Scarlet, lives of the men on-board the satellite, he declines White's proposition to be temporary commander-in-chief of Cloudbase, and therefore, the offer is handed to the honoured Captain Blue. Leaving for a surreptitious destination, which only White has exposed to Lieutenant Green, and with harsh instructions not to publish it to anyone at all, he arrives on-board the USS Panther II submarine, with the alias Robert Snow, where shortly after one of the ensign officers is, with intent, murdered and reconstructed by the Mysterons in their newest play of vengeance to kill Colonel White.
