Star Trek: Voyager: Season 4, Episode 26

4 - 26: Hope and Fear

Stardate: 51978.2 - An alien translator named Arturis can finally decode the Starfleet message received by Voyager five months ago. It directs them to a nearby sector where an unmanned Federation starship waits for them. It's equipped with a propulsion system faster than warp drive, which can bring them home within three months. While the crew members are elated, Seven requests permission to remain in the Delta quadrant. However, everything is not what it seems when alien technology is found aboard the new ship.
