Top surgeon Chen Yuan crashes in the Amazon rainforest and discovers that the future corporation Blackstone is conducting inhumane tests at an "experimental site" there. Drawing on modern medicine and scientific knowledge, he leads the primitive Eaglefeather Tribe, using scalpels, homemade gunpowder, and reverse-engineered future technology to transform from prey into hunter and launch a rainforest empire's counterattack against a future colonial plan.
