Now you see him, now you don't

Kirk is on a ship that is somehow losing its integrity--literally vanishing. While the rest of the party investigating this derelict ship get back safely to the Enterprise, Kirk is stuck as the ship disappears forever! It appears he is dead and Spock officiates his memorial service. However, later Uhura and others begin seeing the Captain in his cheesy space suit as he magically appears and disappears in the ship. Perhaps he really isn't dead after all. Unfortunately, although they want to stay and investigate further, the stupid Tholians arrive and try to trap them forever in a giant space web unless they leave.

This is a space-bound episode and because they never land on any planets or see any aliens face-to-face, this is a duller and more static episode than average. While it isn't bad, it is poor enough to feel right at home with all the other weaker episodes of season 3 (by most every opinion, the quality of the series dropped in this final year).
