In the second episode of the three-part story "The Happiness Patrol," the Doctor (Sylvester McCoy) and Ace (Sophie Aldred) have arrived on Terra, a planet governed by the Happiness Patrol, who punish those not expressing eternal joy by killing them on the spot. Since both the Doctor and Ace have been designated as "Killjoys," they are targeted for extinction by the robotic Kandyman (David John Pope). The only hope for the time-travelers is to foment a rebellion against the smiley-faced dictator, Helen A (Sheila Hancock). Written by Graeme Curry, "The Happiness Patrol, Episode 2" first aired on November 9, 1988. ~ Hal Erickson, Rovi
