Stardate N.G.   A temporal anomaly strikes the U.S.S. Voyager, hitting Chakotay point-blank and splitting different areas of the ship into different time-frames from its history. After the Doctor creates a chronoton serum to counteract the effects of the temporal bolt, Chakotay finds he is the only member of the crew that has free range of the ship. Forging alliances with crewmates from Voyager's past, present and future, Chakotay must find a way to set events back to normal.
