In China, the Amur River’s middle course is called Heilong-jiang, which means Black Dragon. It runs through ancient Manchuria and forms a natural border between China and Russia. Until recently, this was a restricted military zone – restricted for humans but a blessing to wildwoods, wetlands and wildlife. The border between the super-powers is also the reason why the river's flow remains uninterrupted by dams – an increasingly rare situation on this planet. The film shows how China is beginning to recover wild wetlands and woodlands in order to enable the return of wildlife. On the Chinese-Korean border, pristine subtropical jungle surrounds Northeast Asia’s mightiest volcano. From its crater, a natural shrine for consecutive cultures, flows the Amur's biggest tributary, the Songhua or White Dragon River.
