Summary: The Doctor has regenerated for the first time. Ben and Polly are distraught and confused, and Ben tries to see if this really is still the person they’ve known. Ben tries to fit the First Doctor’s ring on his finger, but when it falls off, the Second Doctor says “I’d like to see a butterfly fit into a chrysalis case after it spreads its wings.” The new Doctor, once he is finally able to focus and compose himself, begins fiddling with the TARDIS console. It lands on the planet Vulcan (no, not the one from Star Trek. This was written before that was in Star Trek, but it didn’t air until after Star Trek had first aired. It’s one of those weird coincidences) Upon arrival, the Doctor discovers the body of the Examiner, who was sent by the government because of a new discovery. There is also a swamp composed of mercury outside. They enter the colony’s base and meet the governor and a scientist named Lesterson, who has discovered a capsule that was in the swamp. When they open the capsule, they find Daleks inside. The Doctor wants them destroyed, but Lesterson refuses. He’s genuinely interested in the Daleks. The Daleks claim they are servants, and are even disarmed.
While this is going on, there is a rebel faction who wants to take over the colony. The Daleks play along, but are secretly planning to revive themselves and kill everyone in the colony, even willing to turn both factions against each other if necessary.
