The Tenth Planet Part 1
When the TARDIS lands at a South Pole research base in 1986, the Doctor, Ben, and Polly find themselves caught in a web of intrigue as a mysterious new planet appears, threatening Earth and humanity.
In 1986, the TARDIS materializes near Snowcap Base, an International Space Command facility in Antarctica. The Doctor, along with his companions Polly and Ben, quickly attract the attention of the base's personnel, led by the no-nonsense General Cutler. Their sudden arrival coincides with strange events: Zeus 4, a manned probe on a routine atmospheric testing flight, veers off course, and a new planet appears in Earth's solar system.
The Doctor's knowledge of the mysterious planet piques Cutler's suspicion. While the Doctor tries to warn the base about the impending danger, scientists at Snowcap struggle to understand the new planet's influence on Zeus 4. The probe reports power loss and disorientation but it is feared to be space fatigue from the pilots.
As the Doctor attempts to explain the planet's significance—revealing it as a long-lost twin of Earth—Cutler remains skeptical, choosing instead to contact International Space Command in Geneva. Meanwhile, the crew of Zeus 4 battles increasing power loss and struggles to maintain control.
Back at the base, tensions rise as the Doctor's warnings become increasingly relevant. International Space Command dispatches orders to investigate the new planet and demands information about the intruders at Snowcap. Cutler sends Sergeant and Tito to investigate the hut the team arrived in as a flying saucer lands a short distance away. As they try to enter the TARDIS, silver giants appear. The sergeant fires twice, but is struck down by the lead figure thus leaving their intentions unclear and the Doctor's warnings validated, hinting at an imminent alien threat connected to the mysterious planet.
Events in This Episode
The narrative beats that drive the story
The episode opens at Snowcap Base, an International Space Command facility, tracking the routine atmospheric probe Zeus 4. Simultaneously, the TARDIS materializes nearby, bringing the Doctor, Ben, and Polly into the Antarctic blizzard. Base personnel quickly discover and apprehend the trio, bringing them into the Guard Room for interrogation. General Cutler, the base commander, dismisses their fantastical claims of a spaceship. As the Doctor's group is confined, Zeus 4 begins to report inexplicable orbital deviations and power fluctuations. Scientists at Snowcap confirm the appearance of a new, rapidly approaching planet, causing alarm. The Doctor, having observed the planet, cryptically offers a warning, and later, through a written note, demonstrates foreknowledge of the planet's appearance and characteristics. He reveals the planet is Earth's long-lost twin, a statement Cutler dismisses as a confidence trick. Cutler prioritizes the Zeus 4 crisis and contacts International Space Command in Geneva for further guidance. This act establishes the setting, introduces the main characters, and sets the central mystery of the new planet and the Doctor's suspicious knowledge, laying the groundwork for the unfolding crisis.

Following the Doctor's unsettling revelation and Cutler's dismissal of his claims, General Cutler contacts Secretary General Wigner at International Space Command (ISC) in Geneva. Wigner, initially disbelieving, orders immediate verification of the new planet's existence from other global observatories, confirming the scale of the threat. Concurrently, the crew of Zeus 4 experiences worsening power loss and debilitating physical weakness, struggling to maintain control as the planet's gravitational influence intensifies. Cutler informs Wigner about the "intruders" at Snowcap, specifically mentioning the Doctor's unusual knowledge. Wigner demands more information on the Doctor's group. Growing increasingly suspicious of the Doctor's connection to the unfolding events, Cutler interrogates the trio again, directly linking their mysterious arrival to the crisis. He then orders Sergeant and Private Tito to forcibly investigate the "hut" (the TARDIS) the Doctor's group arrived in, seeking answers by force and setting the stage for a direct confrontation with the Doctor's ship.

Tasked by General Cutler to forcibly investigate the mysterious "hut" where the Doctor's group purportedly arrived, Sergeant and Private Tito venture out into the desolate Antarctic blizzard. The Sergeant attempts to open the TARDIS doors but finds them impenetrable, necessitating a welding torch. He dispatches Tito back to the base to retrieve the tool, leaving himself alone on the desolate surface, exposed to the elements. Moments later, a small, unidentified flying saucer descends silently and lands a short distance away from Snowcap Base. Three tall, shiny, silver-clad figures emerge from the alien craft and begin to advance purposefully towards the TARDIS. The Sergeant, startled and confronting these unknown, silent entities, issues a challenge and fires his gun twice at the lead silver giant in a desperate act of defense. Without hesitation, the alien figure retaliates with a powerful blow, striking the Sergeant across the neck and incapacitating him, leaving him motionless in the snow. The scene cuts to Tito, who returns to the Guard Room, retrieves the welding torch, and prepares to rejoin the Sergeant, entirely oblivious to the violent, life-threatening encounter that has just transpired. This climactic sequence dramatically shifts the narrative from a scientific anomaly and human suspicion to an undeniable, immediate alien invasion, validating the Doctor's earlier, dismissed warnings and leaving the fate of the Sergeant and the base hanging in perilous uncertainty.
The Sergeant, left alone outside Snowcap Base after sending Tito to retrieve a welding torch, witnesses three towering silver-clad figures emerge from a landed flying saucer. His initial confusion and …
