FFF. The Mind Of Evil
The Doctor and Jo attend a demonstration of the Keller Machine at Stangmoor Prison; it is claimed that the machine can extract negative emotions. The Doctor is sceptical, and this seems justified when a prisoner collapses during treatment.
The Brigadier has problems of his own: U.N.I.T. are providing security for the World Peace Conference when documents go missing, and the Chinese delegate is found dead. At the same time Captain Yates is in charge of taking a Thunderbolt missile to be destroyed.
The Doctor and Jo join the Brigadier, and manage to stop the Chinese delegate's aide, Captain Chin Lee, from killing the American delegate. Lee is actually under the control of the Master, who is assuming the guise of Emil Keller.
The Master is using the stored negative emotions from the Keller Machine to cause unrest at the prison, and then uses the convicts to sieze the missile with the aim of destroying the peace conference. The Doctor manages to activate the missile's auto-destruct. The emotions container and machine are presumed destroyed, but the Master escapes ...

Episode 3 : After the Master has the Doctor brought to the prison office, he informs him that he intends to steal a nuclear weapon from U.N.I.T. to blow up the World Peace Conference. As has already been firmly established in the previous two episodes, it is a nerve gas missile; the Master himself even heard this information from having tapped the phones at HQ.
Episode 3 : As the Doctor and the Master have a fist-fight in the prison governor's office they knock over a water carafe, and slip and slide all over the ensuing puddle. This wasn't meant to happen, but they kept it in the finished episode, just because it looked great.
