The episode begins when Kirk and Spock beam onto Elba II, which is a planet where the criminally insane people are kept, to deliver medicine to the Governor, Cory, which is the main medical doctor. But when they get to the planet they discover that one of the mental patients, Garth a former Captain of Starfleet, has taking over the facility with the ability to transform his body to whomever he wishes. Garth will assume the identity of Kirk to take over the Enterprise in order to push the power of his poor moral fiber. But it will be a scene where Spock will have to choose the correct Captain Kirk that will bring the story to a close.
Could never get into this story with the wild chair and the fancy dancing of the painted green Yvonne Craig. The most interesting thing was the way Garth could change into any person desired. If the episode could have stayed with that detail then it would have been a much better show. Instead they went with an unbelievable ending that seemed quickly made. But it was very nice to see that the most apt person on the show happened to be Scott.
