The Doctor is furious when Polly and Ben show up in the TARDIS and tries to explain to them that they’re now stuck with him indefinitely because he still can’t control where the TARDIS lands. They end up somewhere on the shore of Cornwall. Although they’re shocked to be so far out of London, they still don’t believe the Doctor when he tells them that they still don’t know when they are. They go to a church where a man threatens them with a blunderbuss. From the man’s clothes, the Doctor deduces that they are in the seventeenth century. They learn that he’s a churchwarden named Joseph and he’s afraid of a pirate crew that served under a man named Avery. Unfortunately, they also learn that the TARDIS will be submerged in the tide. In gratitude to the Doctor for fixing his dislocated finger, Joseph gives him a strange clue, telling him that the “Deadman’s secret key” is “Smallwood, Ringword, Gurney.” After they leave for the local inn to wait out the tide, Joseph, who was a pirate himself under Avery, is killed by men sent by Samuel Pike, Avery’s successor as captain and who is after Avery’s hidden treasure. Pike’s goons had seen the Doctor and the others and suspect that Joseph sold the secret of Avery’s treasure to them. The pirates abduct the Doctor and wound Ben. Worse, the local squire ends up arresting Polly and Ben on suspicion of Joseph’s murder.
The Doctor manages to charm Pike out of some charitable treatment, as Polly and Ben use twentieth-century technology to convince their jailer that they serve a warlock and escape. After doing their own investigation at the scene of Joseph’s murder, Polly tries to present evidence they found to the squire, only to stumble across Pike and the squire, who has been running a smuggling ring, making a business deal. Meanwhile in the church Ben comes across Josiah Blake, a government revenue agent, but before they can leave the squire shows up with Polly. When the squire accuses Ben and Polly of working for Pike, Blake, who came to investigate reports that the squire was corrupt to begin with, pretends to believe him and takes the Doctor’s companions into his custody. After escaping from the ship, the Doctor comes across Ben, Polly, and Blake, who leaves to get a militia for help. The Doctor figures out that Joseph’s clue referred to names in the local graveyard, but one of Pike’s men, who wants the treasure for himself, arrives and forces the Doctor to tell him the clue. Pike shows up and dispatches the traitor, and tells the Doctor that if he doesn’t help him find the treasure he’ll start massacring the locals. Just as the treasure is found, Blake’s militia appears and successfully fights the pirate crew. Blake and the squire, who was of course betrayed by Pike, defeat and kill Pike. As the battle wraps up, the Doctor, Polly, and Ben slip away back to the TARDIS. After the TARDIS teleports again, the Doctor announces that they’ve arrived at the “coldest place in the world.”
