The beings surrounding the Doctor ask for his help telling him they are Plasmatons before releasing them. The Doctor, Tegan, Nyssa & Captain Stapley encounter Professor Hayter, a passenger on the first Concorde who has resisted the hypnotic control the other passengers have fallen under. Kalid sends a controlled Plasmaton to subdue Nyssa who is being controlled telepathically to broadcast a warning. The Doctor leaves Tegan to look after Nyssa while he, Hayter & Stapley go to the Mausoleum where they find the crew and passengers of the other Concorde engaged in manual labour trying to break into a large object. The Doctor finds his way to the Kalid's control room and confronts him. His power distracted, Nyssa is free and she & Tegan go to the Mausoleum where they are confronted with illusions of Adric, The Melkur & a Terrileptil. Hayter & Stapley free the two members of Hayter's crew, Bilton & Scobie, but all four are transported to the Kalid's chamber and attacked by a Plasmaton beast. Nyssa and Tegan find their way to the source of the Kalid's power and disrupt it, the Plasmaton beast vanishing and Kalid collapsing to the floor. As the Doctor & Hayter examine the Kalid's equipment a familiar voice rings out and out from the decaying form of the Kalid's body steps the Master.
Just dreadful. The music doesn't suit the on screen action, the Plasmatons in their usual form look rubbish, the Kalid just doesn't work and the only decent set in the program, the Kalid's chamber, is ruined when you see the join between walls and floor. Ugh.
The illusions in this episode feature Matthew Waterhouse as Adric. During season 19, 20 & 21 two episodes were shown on consecutive days and to save space in the Radio Times both episodes shared a single cast listing. By having him appear here in a speaking role the character got a credit for the two episodes in that week's Radio Times, which was released before Earthshock 4 aired, so there wouldn't be the slightest suspicion that he would die in the final episode of Earthshock. Reprising his (uncredited) role as the Melkur is occasional Cyberman & the future PC Tony Stamp in The Bill, actor Graham Cole.
