YOU are the youngest scientist in Antarctica. As an expert research scuba diver, you have made discoveries in Antarctica's ice-covered lakes and oceans that have changed the world's understanding of how life can exist in the most extreme environments. After many months away, you are back at the research station. You're about to board a helicopter back to your remote research site when you receive word that one of your colleagues has gone missing. Do you delay your return to help the rescue team, or do you head back to the field to work on your experiment, which could be ruined if you don't return soon? Be careful, the choices YOU make might end in glory, disaster, or certain death.
