The Voyager crew are unwitting research subjects after scientists of the Voth race, saurians who believe they were the first intelligent beings to evolve in the Delta Quadrant, discover the human remains of Voyager crewman Hogan and find a genetic pattern similar to their own. When Gegen, the chief researcher, suggests that based on these findings, the true origin of the Voth is Earth, their leader, Minister Odala, deems him a heretic. To prove his theory, Gegen and his assistant Veer track down Voyager, infiltrate the ship and take their next research subject, Chakotay, hostage.
