In the conclusion of the three-part story "The Happiness Patrol," the Doctor (Sylvester McCoy) sparks a revolution against Helen A (Sheila Hancock), dictator of Terra, where the punishment for not expressing constant happiness is death. Once he has neutralized Helen A's robotic henchman, Kandyman (David John Pope), the Doctor goes to work on the dictator herself -- and he doesn't intend to resort to violence. A poignant ending caps Graeme Curry's teleplay for "The Happiness Patrol, Episode 3," which first aired on November 16, 1988. ~ Hal Erickson, Rovi
