Admiral Janeway took her shuttle to a moon, where she met Miral Paris. Miral introduced Janeway to Koroth, of the House of Koroth. Koroth possesed a chrono-deflector for the admiral, but refused to give it to her when Janeway refused to provide him with information regarding her shuttle's shield modifications.
After Janeway took the deflector, Koroth sent his ship to intercept Janeway's shuttle. Prior to the skirmish, Janeway deployed her shuttle's new armor technology. This technology is capable of absorbing the brunt of any phaser blast.
After fixing the chrono-deflector to her shuttle's hull, Janeway took her shuttle back in time, to aid Voyager in one last encounter with the Borg.
