Doctor Who: The Horns of Nimon, Episode 3 (1980)

In the third episode of the four-part story "The Horns of Nimon," both the Doctor (Tom Baker) and Romana (Lalla Ward) are captured by the Nimon, and prepared for human sacrifice. This pleases demented scientist Soldeed (Graham Crowden), who hopes that by serving the Nimon he can restore the past empiric glories of his home planet Skonnos. The Nimon has a slightly different agenda in mind. Written by Anthony Read, "The Horns of Nimon, Episode 3" first aired on January 4, 1980. ~ Hal Erickson, All Movie Guide
