A pair of aliens named Lal and Thann (who look like they're related
to the Talosians of "The Cage") capture Kirk, Spock and McCoy, and involve
them in a series of experiments that include a mute woman named Gem, who
has empathic abilities which allow her to absorbs the pain and suffering
of others. The aliens are doing so in order to determine whether or not
Gem's race is worthy of being saved from a forthcoming super nova, or if
a neighboring planet is worthier to survive.
This is Metzcat's least favorite episode... can you tell?
