很久以前，開拓者們幾乎踏遍了每一寸未開發的土地。但對某些人來說，仍有個地方是未受人類所侵擾的，那就是太平洋西北部的茂密樹林。這些勇士以樹林為家，他們自立維生並對抗著大自然，追尋著各自的美國夢。他們在他們的林中堡壘狩獵、捕魚、睡覺並從事各種活動。他們將面臨各種危險，從森林大火、閃電風暴、土石流到危險的掠食者。
Long ago, pioneers and explorers were pushed into the last remaining unclaimed territories. But for a few brave souls, there's still one area that remains untouched and primitive: the towering tree tops of the Pacific Northwest. These men call the trees home. These tree people live on their own terms and battle Mother Nature in pursuit of their own American Dream. They hunt, fish, sleep, and do almost anything from their tree forts. They face extreme danger in the form of forest fires, lightning storms, mudslides and predators.
