 A Klingon named Korath has discovered the perfect way to finally get rid of Captain Picard: abduct one of his ancestors from the past and bring this ancestor to the 24th century for execution. This ancestor also happens to be an unnamed member of a tour group in line to ride a Star Trek attraction at the Las Vegas Hilton in our time. Commander Riker and the Enterprise-D gang manage to divert the Klingon temporal transporter beam to themselves in an attempt to return the tour group to their own time.
