Harry's sensor sweeps for space anomalies detect a wormhole which Janeway diverts Voyager off course to investigate. Though a probe is able to determine that the wormhole leads homeward to the Alpha Quadrant, the wormhole is too small to travel through. When the probe is scanned by a ship on the other side, the crew begin using it as a relay satellite and make contact with a Romulan ship. Though the Romulan captain is skeptical of Janeway's claim that Voyager is in the Delta Quadrant, he eventually realizes the truth and offers to help transmit messages home. Later, B'elanna discovers a possible way to beam through the wormhole to the Romulan ship, but this method of returning to the Alpha Quadrant is halted by an unforseeable problem.
