Stardate 51268.4/51425.4: The Krenim scientist Annorax alters history by means of "temporal incursion". When Voyager first encounters a small Krenim patrol ship, their territory is small. But Annorax's eradication of the Zahl homeworld restores the vast Krenim Imperium, without anyone outside his temporal weapon ship noticing the change. Voyager is now attacked by a powerful Krenim warship using chroniton torpedoes to penetrate the shields. The Starfleet ship suffers extreme damage. Seven of Nine devises a temporal shielding based on Borg technology as a countermeasure. Now protected against the chroniton torpedoes but also against changes in the timeline, the crew becomes aware of Annorax's following attempt to eradicate the Garenor homeworld. Annorax notices that Voyager's temporal shielding has disturbed his incursion and he strives to eradicate the Federation ship using his temporal weapon. With Tom and Chakotay captured by Annorax and the ship being damaged beyond repair, only Janeway and a skeletal crew remain on board. In the meantime, Chakotay gains the trust of Annorax. He learns that Annorax strives to restore the lives of his family on the Kyana Prime colony, for whose extinction he is responsible himself. Tom, on the other hand, is outraged about Annorax, and he allies himself with Obrist, one of Annorax's man who is tired of his mission that has been going on for 200 years. When it becomes clear that Annorax is not going to stand down, Chakotay agrees to Tom's plan to transmit a message to Captain Janeway and convince Obrist to get ready to disable the temporal shielding of the weapon ship. Meanwhile Janeway has assembled a fleet of the Nihydron and the Mawasi that conducts an attack on Annorax's ship. Obrist takes down the shields, and Janeway conducts a suicide attack with the badly damaged Voyager. The weapon ship eradicates itself. Since it has never existed, everything is restored to its original state.
