Now that’s more like it.
The Enterprise goes back to a high security facility (q.v. Dagger of the Mind), but they learnt from last time and so there are some effective security restrictions in place.
In a lot of ways the plot of this episode is very similar to that of Plato’s Stepchildren just a few episodes ago. The difference is that this time the guest star has a nice sense of menace and insanity, which makes all of the business between Kirk being made prisoner and finally defeating everyone a lot more enjoyable.
