Terror of the Zygons is the first serial of the 13th season of the British science fiction television series Doctor Who, which was first broadcast in four weekly parts from 30 August to 20 September 1975. It was the last regular appearance by Ian Marter as companion Harry Sullivan. He would later return in The Android Invasion. It was also the last regular appearance by Nicholas Courtney as Brigadier Lethbridge-Stewart.

An unseen force attacks and destroys an oil rig in the North Sea. In rural Scotland the day after the attack, the Doctor, Sarah Jane Smith and Harry Sullivan arrive in a small village where Brigadier Lethbridge-Stewart and U.N.I.T. are investigating the rig's destruction. Huckle, a representative of Hiberian Oil (the company which owned the rig) explains that three other rigs have been destroyed in similar circumstances in the past month. He leads the Doctor, Harry and the Brigadier to Hiberian Oil's headquarters, where survivors of the rig's destruction are having their injuries treated. Meanwhile, another survivor, named Munro, washes up on a shoreline.

At the village's inn, Sarah talks to the landlord Angus, and admires a stuffed deer's head. Angus reveals the head was a gift from the Duke of Forgill, a local landowner, and tells her an old legend about Tulloch Moor, where many people have disappeared in the mist over the centuries. On his way back to the village, Harry sees Munro on the moor, but before Munro can reveal what happened to the rig he is shot dead by Caber, one of the Duke of Forgill's servants. A second shot severely injures Harry. The Doctor returns to the inn and starts work on a radio probe to check for localised signal jamming, but receives a phone call stating Harry has been found injured on the moor. He and Sarah visit Harry in Hiberian Oil's sickbay, where he is sedated and being cared for by a nurse named Sister Lamont.
