Synopsis: The U.S.S. Enterprise pursues an unidentified Class-J cargo ship into an asteroid belt. After the cargo ship's engines overload, the Enterprise beams aboard its captain, calling himself Leo Francis Walsh, and three beautiful women; the Enterprise burns out all but one lithium crystal in the rescue attempt. The Enterprise heads for a lithium mining operation on Rigel Twelve less than two days away.
Captain Kirk learns that the real Captain Walsh is dead, and his identity was assumed by Harcourt Fenton 'Harry' Mudd, who was operating the cargo ship illegally to transport wives for settlers on Ophiuchus Three. With his long criminal record, Mudd is confined to quarters, but he secretly contacts the lithium miners and talks them into trading lithium crystals for Mudd's women as wives.
With the Enterprise's last lithium crystal burned out, Kirk is forced to agree to Mudd's arrangement; the three women get to stay with the miners, and the Enterprise gets its needed crystals, but Kirk takes Mudd into custody to turn him over to authorities.
