Stardate: 5730.2 --The Enterprise comes across a shuttlecraft taken from Starbase 4 on their way to the planet, Arianis. The alien piloting the shuttlecraft is completely white on one side of his body and completely black on the other. The alien claims that he is a political refugee and wishes asylum.
Shortly thereafter, another alien much like the first, except he is white and black on opposite sides, arrives and demands that first alien be handed over to him.

music: Theme song written by Alexander Courage
Goof-- A large string/wire is clearly visible supporting the shuttle model as it enters the Enterprise hanger bay.
Trivia--During the filming of Frank Gorshin and Lou Antonio's run sequences, Gorshin and Antonio collided with one another when neither actor knew the other was striding down opposite ends of the corridor. The camera crew hadn't warned them that their scenes were being shot simultaneously.
Space: the final frontier. These are the voyages of the starship Enterprise. Its five-year mission: to explore strange new worlds, to seek out new life and new civilizations, to boldly go where no man has gone before.
