What would you do if you were confronted with a "kill-or-be-killed" scenario? What if that meant that you had to kill the infant of an alien species to save your own life? And what if the future of the human race depended on your decision? Space colonists from Earth crash-land on a planet orbiting the star Epsilon Eridani and immediately wrestle with an ethical dilemma. They emerge from their stasis pods 33 years older than when they started and must decide whether or not to harvest stem cells from alien infants to counteract the effects of human aging... even though the process will kill the infants. As factions develop among the astronauts, the scientists race ahead with experiments to restore their youthful vigor, and must face the unexpected consequences of their choices.
