 An Earth research team uncovers wreckage and drones from the Borg sphere that attempted to stop Zephram Cochrane s warp flight nearly 100 years ago. The Borg regenerate, assimilate the team, modify their transport and flee Earth. Enterprise answers a distress call too late, rescues "survivors," and Phlox is injected with assimilation nanoprobes. Enterprise catches the transport and Archer must determine whether or not to try to salvage the personnel or stop the Borg efforts before they are out of control.
