Ophelia is an angsty teenager who doesn't seem to take her training on the harsh environment of Saturn's moon seriously. She faces many challenges when forced to accompany her instructor on the supposedly safe trading route to another community. Although her instructor seems like a boring rule stickler at first, she soon realizes maybe he's not as bad as she thought. Through the harsh tundra, storms, and deadly geysers of Enceladus, will they both make it home for Christmas in one piece?
