The Doctor discovers a link to the recumbent stone circle s that are plentiful in this part of Scotland . The stones are thousands of years old , and are soon revealed to hold a terrible secret . Then Mike Yates disappears , abducted by an alien race that has a grievance with humanity . Their intention is to harness the power of the stones in order to take their revenge . For the Doctor and the Brigadier , the race is now on to save their new friend Mike and the entire planet Earth . Plot . An RAF fighter and its pilot disappear while on a training mission over the coast of Scotland . As the story told by the pilot ' s trainer John Morton is rather unusual , UNIT is called in , and the Third Doctor comes along for the ride ( literally , as he brings his roadster Bessie with him ) . There they meet local army lieutenant Mike Yates , who is seconded to UNIT for the duration due to his knowledge of the area ; it ' s the region in which he grew up . Corporal Macrae tells Mike that the pilot , Frank Parry , has been sighted near Inverurie . As the Doctor and Mike drive around the outskirts of Inverurie , they find Parry at the Easter Aquhorthies stone circle — but shortly thereafter , Parry reaches for the recumbent stone , and dies after putting his palms on it , apparently due to an energy discharge . Stumped for leads , the Doctor chooses to take another plane and retrace the pilot ' s flight plan under similar circumstances ; unknown to him , the Brigadier follows behind in a helicopter . The Brigadier ' s caution is rewarded ; the Doctor sees many of the stone circles light up with power , and then a massive ball of power is released , streaking into space — and wrecking his jet in the process . He crashes safely into the ocean , and is rescued . After some further investigation , Mike returns to one of the circles . He is immediately incapacitated , and is taken prisoner . His captors are Armidian s from a planet named Tharos ; only a few of them remain . In the course of painfully interrogating him , they reveal that they came to Earth a few thousand years earlier on a survey mission for natural resources ; they were attacked by the local barbarians , and several of their number were killed . The remaining four Armidians were forced into stasis for the sake of their survival ; but recent roadwork disturbed their stasis pods , awakening them . Now they want revenge for what they considered an act of war . It was they who built the stone circles , as data collection and transmission points ; they have an affinity for igneous rock . They can harness the power of such rock using the Tharon stone that is native to their own world . Meanwhile , the Doctor and the Brigadier are searching the area of Mike ' s disappearance . After spotting a boy called Davy Ross holding a flight helmet , they discover a dilapidated shed ; but oddly , they feel a strong urge to ignore it . The Doctor determines that the shed has a perception barrier , which diverts attention ; he pushes through it and opens the shed , and finds the now - gutted remains of the missing jet . Davy tells the Doctor and the Brigadier about the abandoned house inhabited by " beasties " , which Davy can see due to his young mind . They take a squad of soldiers in , and find Mike being interrogated . They discover that the vengeful aliens now only wish to kill everyone on Earth ; they have already sent a distress signal to their homeworld . However , the Doctor informs them that , sadly , their world has ceased to exist during their long sleep . Despite the Doctor ' s attempts at diplomacy , a battle erupts , and one of the Armidians is killed ; their leader Garlin Munn teleports them out of the house , but Mike breaks free of the Armidians before he can come with them . Before moving on , the Doctor receives a message via a telephone recording . . . and it appears to be from his future self . He learns that , despite the Brigadier ' s desire to end the encounter by force , the Doctor must somehow save the Tharon stone from destruction and give it to Professor Reynard of the Royal Society — and he must not tell the Brigadier ahead of time , as that would force his hand . The Doctor determines that , given the affinity for rock , the teleport took the aliens to one of the circles . UNIT quickly locates them , and the Doctor and Yates race to the scene . In the end , the Doctor tells Yates to earth the stone using the wire fencing , returning its power to the Earth from which it was taken ; the last of the Armidians die in the encounter . Mike Yates is requested by the Brigadier to join UNIT full - time , and granted a promotion to Captain in the process . References . " to be added " Continuity . " to be added "
