 Voyager answers a distress call from an alien device with bio-neural circuitry and sentience. Voyager beams the  survivor  aboard, and further scans show it is a highly-sophisticated warhead capable of mass-destruction. The Doctor, who speaks it s technical language fights for it s rights when the rest of the crew seeks to distance the ship before the warhead fulfills it s purpose. His efforts are unappreciated when, facing shut down, the warhead s intelligence commandeers The Doctor s program and several ship s systems. It s ultimatum is clear: Voyager will deliver the warhead to it s target or be destroyed.
