We want you to do it again." These words, spoken to Brian Robeson, will change his life. Two years earlier, Brian was stranded alone in the wilderness for 54 days with nothing but a small hatchet. Yet he survived. Now the government wants him to go back into the wilderness so that astronauts and the military can learn the survival techniques that kept Brian alive. Soon the project backfires, though, leaving Brian with a wounded partner and a long river to navigate. His only hope is to build a raft and try to transport the injured man a hundred miles downstream to a trading post--if the map he has is accurate.


「我們希望你重現當時的情況。」這句話將改變布萊恩‧羅伯遜的人生。兩年前，布萊恩獨自在荒野受困了 54 天，身上只有一把小斧頭，卻奇蹟似地活了下來。現在，政府希望他能重返荒野，教導太空人與軍隊求生技能。但計畫很快變了調，布萊恩只能和他受傷的夥伴，沿著漫長河找尋出路。眼前，兩人僅存的希望，便是由布萊恩建造一艘木筏，載著受傷的夥伴順流而下到距離一百哩遠的交易站——但前提是地圖得是正確的！
