Tread Perilously continues its adventure in time and space with the Jon Pertwee era Doctor Who story "Death to the Daleks." The Doctor and Sarah Jane Smith find themselves on planet Exxilon out of power and out of answers. The Daleks also land on the planet, but also find themselves out of power. Turned into middle management, the Daleks order the natives and some marooned humans to mine an ore while the Doctor and a new friend learn the secrets of Exxilon's mysterious living city.
Erik and Justin discuss the odd similarities to "The Dominators," Pertwee's performance and both stories' slight case of senioritis. Terry Nation's strengths and weaknesses as a writer also get some examination. They plot the next big Dalek TV show: "Daleks of the Old West" and consider what happens when a Dalek becomes the boss of crusty gold prospectors. They also suggest the possibility that Nation was done with the Daleks when writing this story.
