The episode was written by Lee Cronin and Oliver Crawford, directed by Jud Taylor and novelized in Star Trek 5 by James Blish.
On a mission to decontaminate the planet Ariannus the Enterprise retrieves a stolen spacecraft with one person aboard—Lokai—who is white on the right side of his body and black on his left side. An invisible spacecraft comes straight toward the Enterprise and leaves its pilot aboard before being destroyed. The pilot is Bele who is black on the right side of his body and white on his left side. Bele is a police commissioner from the planet Cheron V who has been chasing Lokai for 50,000 years across the galaxy. Although slavery was abolished on Cheron the ruling class is Bele's color and the ruled class is Lokai's color. Lokai tries to enlist the Enterprise crew in his crusade and Bele claims to be superior color to Lokai to James T. Kirk and Spock. When the Federation refuses to honor Bele's request for custody of Lokai, Bele with the power of his will tries to hijack the Enterprise to Cheron in a standoff with Kirk who for his part activates the self destruct—which is only averted when Bele agrees to turn over control of the starship to Kirk.
When Ariannis is decontaminated, Bele hijacks the Enterprise again—after destroying the self destruct with his will. On arrival at Cheron, the ships sensors show that the entire humanoid population has wiped out one another. Lokai transports himself down to Cheron followed by Bele.
