Stardate 43917.4: Famed Vulcan Ambassador Sarek, father of Spock, beams aboard the Enterprise to be transported to his final diplomatic duty. But he is suffering the initial symptoms of a mind-deteriorating Vulcan disease and his Vulcan telepathic skills inadvertantly project violent, irrational impulses in the crew’s minds. Picard decides to risk a mind-meld to stabilize Sarek for the negotiations, but the captain risks his own sanity.
