"Voyager" begins a running battle with many Krenim ships over a period of two months, suffering heavy damage and casualties. During one attack, Seven of Nine uses an unexploded Krenim chroniton torpedo to devise a method of shielding "Voyager" against the weapons; however, the weapon partially explodes, blinding and severely burning Tuvok. When utilized, the shielding also affects the temporal waves in the region, attracting the attention of the Krenim "time ship", the large vessel that is causing the disruptions. Krenim scientist Annorax (Kurtwood Smith) built the ship to cause "temporal incursions" to be used to erase events from history to strengthen the Krenim Imperium. However, a prior incursion caused a plague that killed millions of Krenim, including Annorax's wife, and he has been seeking a full restoration of his species for the past 200 years. Annorax decides to destroy "Voyager" due to the temporal distortions caused by its shields. The crew escape as "Voyager" is faster, but more damage to the ship ensues. Janeway orders all but the senior staff to abandon ship. She and the senior staff intend to rescue Commander Chakotay (Robert Beltran) and Lt. Paris (Robert Duncan McNeill), who were abducted by the time ship.
