The one with Gem, an empath who can absorb injuries and pain into her own body.
I actually haven't seen this episode many times, possibly only once. I think the BBC didn't used to show it due to the torture and violence. It is very similar to a 1963 episode of "The Outer Limits" called 'Nightmare' in which a series of senseless brutalities are carried out on Earthmen as a test, with the participation of friendly aliens called "Ebonites". As in 'The Empath' the sets in 'Nightmare' were very sparse - and both were directed by John Erman.
The episode does bring out the nobility and self-sacrifice of Kirk, Spock and McCoy as the each try to protect one another.
