Help with eps I haven't watched..

[predatrix.livejournal.com]

With the help of my local library and Lovefilm (DVD rental library) I have caught up with a few classic Who eps so far.

At the moment want to write a response to a particular request on the kinkmeme about _Planet of Fire_, so I borrowed a boxed set of _The King's Demons_ and _Planet of Fire_ from the library and _The Five Doctors_ from Lovefilm.

Since I probably don't want to spend the effort of waiting for/tracking down the intermediate 4 eps between King's Demons/Five Doctors and Planet of Fire, *what exactly happens?*

(I seem to be just watching the eps with the Master in trying to get the "voice' right and how he and the Doctor play off each other. Since there are (according to the Beeb) about 600 old-skool Who eps I tend to rely on my memories from original broadcast apart from that)

Hope someone can help, at least with a rough idea of interesting/important stuff that goes on in those eps.
