The scene of Harry getting blown into space alone makes this episode worthwhile. Really though, apparently the Viidians are tailing Voyager too this whole time in order to harvest a 150 people's organs... or their territory simotaneously spreads for two years along with the Kazon... yeah.
This episode is basically like drugs for Janeway fans. It gets them euphoric and dellusional both at the same time. Bunch of random stuff going on, but really you basically knew how it was going to end. Though this is a more creative push of the reset button than usual.
