As The Doctor and Kes treat three injured aliens whose ship was detected adrift in space, one of them—an egomaniacal political extremist named Tieran—dies, but not before he transfers his own mind to the body of Kes, controlling her and accessing her own Ocampan powers. Then, Kes/Tieran launches a shuttlecraft and makes a coup attempt on his home planet of Ilari.
