Doctor Who (1963)

S20E15 Terminus (3)

The Doctor and his companions, seen as neither lazars nor handlers, are mistakenly identified as investigators, prompting the embittered Valgard to confront Eirak for control of the handlers. Simultaneously, the imposing, canine creature Garm drags a frightened Nyssa away for "treatment." In another development, Bor emerges from the restricted zone with intriguing information regarding the ship's status.
