Doctor Who and The Silurians Part 1
When a research center built in prehistoric caves experiences power losses and strange personnel issues, the Doctor and Liz investigate and uncover a terrifying threat to humanity's existence from an ancient reptilian race.
The Doctor and his companion Liz are summoned by the Brigadier to Wenley Moor, where an atomic research center is experiencing unexplained power losses and unsettling incidents among its personnel. The center, built within a network of caves, is on the verge of a breakthrough in providing cheap and safe atomic energy, but the increasing problems threaten to derail the project.
The Doctor, with his keen intuition, quickly suspects that the issues are more than mere technical malfunctions. He discovers that some of the affected personnel have worked in the cyclotron room, the deepest part of the facility closest to the caves. A technician named Spencer, who went potholing with another technician named Davis, has been traumatized and is painting prehistoric cave drawings. Davis, the other technician, was found dead in the caves with strange claw marks, an incident the Doctor finds particularly curious.
As Liz delves into the personnel records, she finds an unusually high rate of minor neuroses among the staff, specifically those who worked in or frequently visited the cyclotron room. She herself experienced a feeling of oppression and terror while there. The Doctor connects these events to the caves, suspecting that the root cause lies beneath the surface.
Meanwhile, Major Baker, the station security officer, grows suspicious of the Doctor due to his mysterious background. Quinn is observed acting suspiciously as well. Despite the growing unease, Doctor Lawrence, the director, is primarily concerned with pushing the research forward, even as the power fluctuations become more dangerous. They initiate program two three six, with supplementary tests. However, during a critical phase, power levels become erratic, and one of the technicians, Roberts, freezes up, seemingly paralyzed by fear. Dawson tries to shut down sector three, but Roberts snaps out of his trance and begins throttling her, and the Doctor shut downs sector three himself.
As chaos ensues and the power fluctuations intensify, the Doctor's suspicions deepen. He realizes that the cave system is at the heart of the mystery and that something ancient and powerful is awakening within. He connects the death of Davis, the trauma of Spencer, and the unease felt by the scientists, the drawings of primitive humanoid creatures, all hints of a danger long-dormant awakens to threaten Earth's future.
Events in This Episode
The narrative beats that drive the story
The episode opens with two potholers, Spencer and Davis, exploring a deep cave system. Davis encounters and is violently attacked by a tall, amphibian-like creature, while Spencer flees in terror, establishing an immediate, tangible threat. The narrative shifts to the UNIT garage, where the eccentric Doctor is introduced, working on his vintage car, Bessie. Liz Shaw delivers an urgent summons from the Brigadier to Wenley Moor, an atomic research center built into prehistoric caves, experiencing unexplained power losses and personnel issues. Despite his initial reluctance, the Doctor agrees to investigate when Liz mentions the caves. At the center, the Brigadier briefs the Doctor, Liz, Lawrence (the director), Quinn (Lawrence's second-in-command), and Major Baker (security). The core problems are identified: high rates of personnel neuroses, absenteeism, and critical power fluctuations. Liz is tasked with personnel, the Doctor with the scientific angle. While touring the cyclotron, Liz experiences a feeling of dizziness and oppression. The Doctor learns of the potholing accident involving Spencer and Davis, noting torn pages in the power log previously maintained by Spencer. Liz's research into personnel files reveals widespread mild neuroses, particularly among those working in the cyclotron room. The Doctor then insists on seeing Spencer, who is found in sickbay, traumatized and compulsively drawing prehistoric cave art, including a reptilian biped with three eyes. When the Doctor attempts to engage him, Spencer violently attacks, revealing a deep-seated fear. The Doctor deduces Spencer’s mind has been thrown back "millions of years," indicating an ancient, non-human source for the trauma and the wider mystery. This act establishes the setting, introduces the main characters and the central mystery, and provides the first concrete, if cryptic, evidence of the ancient, terrifying threat.

Following the Doctor's unsettling encounter with Spencer, the narrative deepens the mystery and escalates the immediate danger. Quinn and Dawson are observed in a hushed, anxious conversation, revealing their complicity or foreknowledge of the underlying issues, with Quinn emphasizing the "knowledge" to be gained as worth "any risk." This exchange introduces a layer of human intrigue and potential cover-up, suggesting the problems are not merely accidental. Meanwhile, Major Baker, the security officer, expresses suspicion of the Doctor due to his lack of official records, while simultaneously proposing that the facility's issues stem from internal sabotage. The Brigadier, though dismissive of the Doctor's "cave drawings" as evidence, acknowledges the possibility of sabotage regarding the missing log pages. Lawrence, the director, remains singularly focused on pushing the research forward, prioritizing the "program two three six" despite the ongoing disturbances and UNIT's presence, creating a tense atmosphere of impending crisis. During a critical phase of this program, a sudden, severe power fluctuation grips the cyclotron. Technician Roberts, while monitoring the power, freezes in a state of terror, then violently assaults Dawson. The Doctor, witnessing the escalating chaos, intervenes decisively, manually shutting down sector three to prevent a catastrophic meltdown. This incident marks a significant escalation, demonstrating the direct, violent impact of the unknown force on the facility's personnel and operations, transforming the abstract threat into an immediate, life-threatening emergency.

In the aftermath of the cyclotron incident, the Doctor and Liz consolidate their findings, drawing crucial connections that clarify the nature of the threat. Liz reports a "terrifically high rate of minor neuroses" among personnel, specifically those who worked in the cyclotron room, noting her own experience of "oppression, almost terror" while there. The Doctor synthesizes these observations, concluding that the phenomenon selectively affects humans and that the cyclotron room, being the deepest part of the center and nearest to the caves, is central to the mystery. He explicitly links all the disparate clues: Davis's death, Spencer's traumatic regression, and the widespread neuroses, all pointing back to the enigmatic caves. The final, pivotal piece of evidence emerges when Liz presents Davis's police report. The report details "unusual abrasions on the body, strangely resembling scratches or claw marks," which were presumably caused during a fall. The Doctor immediately recognizes the significance of "claw marks," confirming his growing suspicions about a physical, non-human assailant. This conclusive evidence solidifies the existence of a dangerous, ancient reptilian creature lurking within the caves, responsible for the escalating incidents and personnel trauma. The episode ends on this revelation, leaving the audience with a clear understanding of the immediate, terrifying threat and the Doctor's determination to confront it.
