Picard goes to Vulcan to visit Sarek because his son Ambassador Spock has gone missing. Intelligence reports suggest he may be on Romulus, and it seems the Ferengi have gotten into the Vulcan ship parts business.

This two-part episode is dedicated in the memory of Gene Roddenberry, who passed on October 24th 1991. This is also a cross promotion with the upcoming feature film Star Trek VI: The Undiscovered Country.
