These Are the Voyages....
"These Are the Voyages..." is the series finale of the American science fiction television series Star Trek: Enterprise. The episode, which first aired on the UPN network on May 13, 2005, is a frame story, where the 22nd-century events of Star Trek: Enterprise are recreated on a 24th-century holodeck on Enterprise-D from Star Trek: The Next Generation. Featuring guest stars Jonathan Frakes, Marina Sirtis, and Jeffrey Combs, the episode has Commander William Riker grappling with making a difficult admission to his commanding officer about a cover-up. Riker turns for guidance to the simulated events of the year 2161, when the crew of Enterprise travels home to Earth for the formation of the United Federation of Planets and Commander Trip Tucker, played by Connor Trinneer (pictured), saves the captain's life. UPN and Paramount had announced in February 2005 that the fourth season would be the show's last. Reaction to the series finale was negative, although it attracted 3.8 million viewers.
