The episode begins with the TARDIS materializing on the Moon in the year 2049. The Doctor, played by Peter Capaldi, is accompanied by his companion Clara Oswald, portrayed by Jenna Coleman, and a new character, a young woman named Courtney Woods, who is a student at Clara's school. The Doctor is initially excited about the prospect of exploring the Moon, but he quickly realizes that they are not alone. They discover a lunar base that is inhabited by astronauts who are investigating strange occurrences on the Moon's surface.

As they explore the base, they learn that the astronauts have been experiencing mysterious and dangerous events, including the sudden appearance of large spider-like creatures. The crew is on high alert, and tensions rise as they try to understand what is happening. The Doctor, Clara, and Courtney are soon confronted by the astronauts, who are skeptical of the Doctor's intentions. The Doctor attempts to gain their trust, but the situation becomes increasingly dire as the creatures begin to attack.

The astronauts reveal that they have been monitoring a large egg-like structure on the Moon, which they believe is the source of the disturbances. The Doctor, intrigued, leads the group to investigate the egg. As they approach it, they discover that it is pulsating and seems to be alive. The Doctor theorizes that the egg is connected to the Moon's lifecycle and that it may be a form of alien life. Clara, however, is more concerned about the immediate danger posed by the creatures and the astronauts' safety.

As the group debates what to do next, the situation escalates when one of the astronauts is killed by the creatures. The remaining crew members panic, and the Doctor realizes that they must act quickly to prevent further loss of life. He decides to take a more aggressive approach and confronts the creatures directly. The Doctor uses his sonic screwdriver to create a distraction, allowing the group to escape back to the lunar base.

Once inside the base, the Doctor and Clara have a heated argument about the best course of action. Clara is frustrated with the Doctor's detachment and his willingness to sacrifice lives for the sake of knowledge. The Doctor insists that they must understand the situation before making any decisions. Clara, feeling the weight of the lives at stake, challenges the Doctor's authority and demands that they take immediate action to save the remaining astronauts.

The group learns that the egg is about to hatch, and they must make a critical decision: whether to destroy the egg and potentially kill the creature inside or to let it hatch and face the unknown consequences. Clara, feeling the pressure of the moment, takes charge and decides that they should let the egg hatch. She believes that the creature deserves a chance at life, despite the risks involved.

As the egg hatches, a massive creature emerges, revealing itself to be a large, spider-like being. The creature is initially aggressive, but the Doctor realizes that it is not inherently hostile. He attempts to communicate with it, but the situation becomes chaotic as the astronauts react with fear and aggression. Clara, determined to protect the creature, stands between it and the astronauts, pleading for them to understand that it is not their enemy.

In a climactic moment, the Doctor reveals that the creature is actually the Moon's reproductive system, and its hatching is a natural part of the Moon's lifecycle. He explains that the creature will eventually leave the Moon and that it is essential for the balance of the ecosystem. Clara, now fully invested in the creature's survival, makes a bold decision to trust the Doctor's judgment and allows the creature to escape.

The episode reaches its emotional peak as Clara confronts the Doctor about his choices and the consequences of their actions. She expresses her anger and disappointment, feeling that the Doctor's detachment has led to unnecessary suffering. The Doctor, in turn, reflects on his own decisions and the weight of his responsibilities as a Time Lord.

In the aftermath, the creature successfully leaves the Moon, and the astronauts are left to grapple with the events that have transpired. Clara and the Doctor return to the TARDIS, but their relationship is strained. Clara is left questioning her place alongside the Doctor and the morality of their adventures. The episode concludes with the TARDIS dematerializing, leaving the audience with a sense of unresolved tension between the characters.
