The Doctor (Tom Baker) and Leela (Louise Jameson) materialize near the lighthouse of Fang Rock, a small English seacoast town in the early 20th century. The two time travelers quickly make friends with lighthouse keepers Reuben (Colin Douglas), Vince (John Abbott), and Ben (Ralph Watson), who are humorously contending with that newfangled invention known as electricity. But the fun comes to an abrupt end when Ben suddenly and mysteriously disappears. Written by Terrance Dicks, the four-part "The Horror of Fang Rock" launched Doctor Who's 15th season on September 3, 1977. ~ Hal Erickson, Rovi
