Fifteen years after the Starship U.S.S. Voyager crashes into a desolate ice planet, Commander Chakotay and former Ensign Harry Kim, sole survivors of the tragedy, steal the Delta Flyer from a Federation shipyard and return to the U.S.S. Voyager's frozen hull. Aided by Chakotay's striking love interest, Lieutenant Tessa Omond, Chakotay and Kim are hotly pursued fugitives with hope that somewhere embedded beneath the ice, they'll retrieve the only tools they believe can change the fate of their long-dead fellow crew members.
