Africa is a land of giants. Its powerful rivers sculpt the earth and form impressive valleys and waterways that are home to many imposing and powerful inhabitants. These are the rivers where massive elephants and hippos live, feed and drink, and where ancient crocodiles hunt and breed. They share the rivers with porcupines, the martial eagle, and the leopard.

Pei Duobao receives a mysterious letter from his hometown and returns to Hanjiang Village with his daughter. The letter-writer unexpectedly drowns in the river and Pei Duobao's dead wife's grave is dug up by a demonic formation. Rumours spread that there is a sexy female ghost in the form of a fish monster that eats people's hearts and hooks their souls. One after another, people begin to die in the village, in the same way as the "three mountain gods" described in ancient books. The evil gradually overwhelmed the entire village of Hanjiang, and everyone believed that evil spirits were coming and that they would all be sacrificed and no one would be spared.
