The 72nd episode of the prequel spinoff Star Trek: Enterprise airs on UPN. 
A battered duplicate of the Enterprise, apparently crewed by the descendants of Archer’s crew (and led by Lorian, a descendant of T’Pol and Trip), emerges through a temporal rift. Lorian and his crew recount a grim history for the crew of Archer’s Enterprise: an anomaly sucked the ship into the past, and despite the best efforts of the crew’s descendants Earth lost the war with the Xindi, only T’Pol is still alive – and the crew of “tomorrow’s” Enterprise must return to their own future to restore the timelines. But first, Lorian wants something from Archer’s ship that could strand the Enterprise’s original crew – and stop them from preventing the events that led to Earth’s destruction in the first place.
