The Doctor’s regeneration and recovery come at an inopportune time for the Brigadier, who has to try to solve a series of crimes related to the top-secret plans for a disintegrator gun. Sarah, researching a story about the equally top-secret Think Tank organization, is introduced to a gigantic robot which could be the perpetrator of the thefts and killings – despite the scientists’ horrifying demonstration that the robot could not kill Sarah. The Doctor, recovering slowly and aggravating the Brigadier with his unpredictable new personality, discovers that the Think Tank scientists are doing much more than research – they’re planning on taking over the world and culling the human herd of those not up to genius standards.
