It’s a Doc in a box! Our brand new Doctor gets carried away while The Master seemingly gets his plans A and B mixed up
The Doctor is a bit unsteady after his regeneration and needs the help of his three companions, yes THREE companions, to get back to the TARDIS and rest up a bit in the Zero Room: a nice neutral space that’s not troubled by the normal comings-and-goings of the rest of the universe. One small problem, The Master managed to grab Adric before he made it back to the TARDIS and is planning to use his immense mathematical genius (well, he does have that badge after all) to lay yet another trap for The Doctor.
A thwarted attempt at destroying the TARDIS and its crew, by sending them to the point of the Big Bang, leads them on a mission to get Doc to Castrovalva so he can get the nice-and-boring rest he needs to finish his regeneration. Doc still needs all of the help he can get, so Tegan and Nyssa are left having to literally carry the burden of responsibility and get Doc to yet another mountain castle. It’s obviously not going to be plain sailing when some tribal-looking folk show up and cause everyone to get separated. Now the TARDIS crew needs to reunite, find Adric, and work out what cunning plan The Master obviously has up his very well-tailored sleeves.
