Synopsis:

Kirk, Chekov, and Uhura disappear from the transporter pad and reappear on a planet where they are to be trained as thralls to fight for the benefit of their keeper. Spock, back on the Enterprise must find a way to locate the missing trio and begins a search for them.   Meanwhile the three must find a way to survive and conquer the situation they are in.

This is also a pretty fun show to watch especially if you enjoy watching Kirk mix it up with bad guys.  It also has a bit of humor and a very beautiful woman who, of course, falls for Kirk.   The matte paintings, while reused from an earlier episode, make for an interesting shot when Kirk confronts the brains themselves. Although this isn't an excellent episode it is a good one and well worth watching.
