In the year 2035, where robots are common and abide by the three laws of robotics, a techno-phobic cop investigates an apparent suicide. Suspecting that a robot may be responsible for the death, his investigation leads him to believe that humanity may be in danger.

While on routine patrol, Captain Jean-Luc Picard gets word from Starfleet Headquarters that the Borg, an insidious race of half-machine, half-organic aliens, have entered Federation Space and are on a direct course for Earth. Violating direct orders to remain uninvolved, Picard leads the newly commissioned USS Enterprise E into Starfleet's massive assault against their deadliest foe. Captain Picard and his crew pursue the Borg back in time to stop them from preventing Zefram Cochrane from initiating first contact with alien life.
