Upon returning from the Gamma Quadrant, the Ganges
, with Dax and a subordinate on board, suffers total power failure. The Runabout makes it to one of the docking ports, and Commander Sisko and Major Kira try to open it to no avail.

. Once the door is open, the crew finds that the passenger is Vash, the close friend of Enterprise
Captain Jean-Luc Picard, who had not been seen since she went on a tour of the Universe with Q.
