Three time machines in one infinitesimal speck of space and time! Tsk. Of course, a coincidence is possible—but hardly likely.
They just don’t make them like they used to. The multi-episode story structure used by Doctor Who allowed quite a bit of flexibility when planning a season, and while most stories of the First Doctor’s era fit into the standard four-episode format, one story in particular stretched the limits: Terry Nation and Dennis Spooner’s twelve-episode epic “The Daleks’ Master Plan” (Story Production Code V), which first aired in weekly installments from November 13, 1965 through January 29, 1966. Nothing like it had been seen in Doctor Who before. Except, um, Terry Nation’s “The Chase” and “The Keys of Marinus,” six-episode stories from which the structure of “The Daleks’ Master Plan” is cribbed.
Both “The Chase” and “The Keys of Marinus” feature whirlwind tours of disparate locations, either climactic extremes (jungles, deserts, acid oceans) or quasi-realistic settings played for laughs (top of the Empire State Building, an animatronic house of horrors). So too with “The Daleks’ Master Plan”—the deserts of ancient Egypt; the lush jungle of planet Kembel; the swamps of planet Mira; northern England at Christmas; the, ah, manicured cricket lawns of The Oval; and 1920’s Hollywood are all stops for the TARDIS in this story. And why does the TARDIS flit from place to place? Because it’s being chased through time and space, not just by Daleks (as in “The Chase”) but by the Mark IV TARDIS of the Meddling Monk, also known as “The Time Meddler,” because, as a Dennis Spooner creation, he’s of course in this one, too. Can’t let Nation and his Daleks have all the fun.
Still, even if we know, broadly, what to expect from a Terry Nation story, “The Daleks’ Master Plan” works, well, masterfully, with but few exceptions. The story starts somewhat slowly, with the usual Nation technobabble—in short order we are introduced to two different types of spacecraft by brand name (the Spar 7-40 and the Flipt T4) and both ultraspace and ultrasonics, neither of which get any explanation. But most importantly, we are introduced to Mavic Chen (Kevin Stoney), the idolized Guardian of the Solar System (essentially the leader of all humans), whom we quickly find to be in league with the Daleks. Why rule a mere solar system, when you can rule whole galaxies?
Meanwhile, the Doctor desperately needs medicine for a wounded Steven and lands, by happenstance, on the planet Kembel, last seen as the location of a secret Dalek base in “Mission to the Unknown.” Before long, the Doctor, Katarina (picked up in ancient Troy during “The Myth Makers“), Steven, and a headstrong Earth security agent named Bret Vyon (future Brigadier Nicholas Courtney) stumble into a conference being held by the Daleks with representatives from several different galaxies. It’s at this conference that the Daleks’ Master Plan is unveiled.
And, as with most Dalek plans, it’s actually kind of stupid.
