The plot isn't too shabby here, either -- that shuttle flies through an organism that sort of looks like a thundercloud in space, complete with lightning, which ends up infecting the shuttle crew. We can tell because they've got some interesting-looking white scales/fungus on their faces, and they all utter another Bob Baker/Dave Martin catchphrase: "Contact has been made." But what's more exciting than that is that the TARDIS also passes through the organism, and the Doctor is also infected. So not only do we get a possession story, but we get one in which the Doctor himself has been compromised. Of course, it being the Doctor, he's able to resist it somewhat, but even he's not totally immune. Thus as we see the Doctor and Leela exploring the Titan base in response to a mayday signal, we see him losing the struggle against the Nucleus of that space organism as he prepares to shoot down Leela...
Leela, for some reason, is completely unaffected by this creature, and so she's able to help the Doctor, even as he continues to struggle against the Nucleus (he's able to stop himself from shooting down Leela, for instance). His only help lies at the Bi-Al Foundation, on an asteroid in the main asteroid belt. It's not as nice a set (being another one of those white "space" sets we tend to get in future stories), but it's still all right. That said, the "reformed" English spelling on everything -- so, for example, the word 'exit' is realized as 'egsit' -- is not only rather poorly thought-out (such as with the letter 'i' representing two or three different sounds) but it's not even consistent -- Titan has an 'airloc', while Bi-Al has an 'airlok'. So it's a nice idea but it hasn't been properly worked out, and thus the result is either just strange or simply awful (depending on your point of view). Oh, and all the dialogue refers to things like "level X4", while the signs say '4X'.

There's also some stuff about "circus" cloning tricks ("circus" because the clones don't last very long) and using this to make duplicates of the Doctor and Leela that can be shrunk down and injected into the Doctor to take the fight to the Nucleus; a bit of confusion about why Leela is immune (the Doctor thinks it's because Leela is all instinct, and the organism needs intellect to thrive, while Marius seems to believe it might be a simple antibody); and the possessed humans smashing a shuttle into the Bi-Al Foundation (yeah, that will keep the Nucleus safe). It's decently exciting, even if not particularly inspired -- we'll have to see what happens in the last two episodes, to learn if they achieve or squander the potential that this set-up has. That said, injecting the Doctor and Leela clones into the infected Doctor isn't the most encouraging sign...
