A mysterious signal lures the "Starship Voyager" to an uncharted sector of the Delta Quadrant - and an enigmatic ghost ship floating adrift in space. Janeway mounts an investigation, hoping the alien ship may hold a clue to the whereabouts of the caretaker's long lost ship and his mate - the only known entity with the power to send the "USS Voyager" home.
The ghost ship appears deserted, but soon a strange presence casts an eerie spell over the hearts and souls of the crew. Unless Janeway can solve the vessel's mystery, "Voyager" itself may succumb to its haunting song . . .
