After Voyager is nearly consumed by a massive ball of energy, Janeway launches a probe of the phenomenon and a search for a missing 300-year-old U.S. spacecraft trapped inside the energy field - a vehicle used for the first manned mission to Mars in 2032 - a risky maneuver that might cost the lives of the shuttle crew. As Voyager shadows the powerful anomaly known as the Graviton Ellipse, Seven of Nine reluctantly joins a fascinated Paris and Chakotay on the shuttle as they look for the legendary Ares Four, the command module from the first manned mission to Mars. However, once found, the attempt to retrieve the craft and the body of the noble pilot proves treacherous.
