Stardate: 49447 Voyager encounters the debris field of a destroyed ship. Evidence points to a Cardassian drone, a weapon of mass destruction, that was taken over by Torres to work for the Maquis and destroy a Cardassian fuel depot while she was still in the Alpha Quadrant. Somehow, the drone has been tossed into the Delta Quadrant where, now working with a faulty computer system, it has resumed its search for the Cardassian target that is now over 70,000 light years away.
