When radiation sickness appears in Melbourne, people begin lining up for government-issued suicide pills. After Mary and their small daughter Jenny fall ill, Peter and his family share a final moment before taking their doses together, Peter sorrowfully injecting his child. Osborne races around the Phillip Island Grand Prix Circuit and finally crashes his car at Turn 10, resulting in a fiery death. With most of the "Charleston's" crew members developing advanced radiation sickness, they ask to take the submarine on one final voyage to San Francisco. Though they know they are unlikely to survive the trip, they wish to die together on the "Charleston", the only real home they have left. Towers agrees, apparently abandoning Moira to be with his men. As Moira, about to take her own suicide pill, watches the "Charleston" sail away, she is joined by Towers after all.
