After hearing many more reports of attacks, Jeremy becomes determined to face this beast, which can glue itself to the river bottom like a suction cup.

After nearly being capsized in a storm, Jeremy hears reports of small toddlers and children being eaten by the fish, known locally as "Mazunda," as well as a fisherman being dragged to the depths beneath the dam.

Travelling all over the Zambezi, Jeremy gains access to the prohibited waters directly beneath the dam, where he finally hooks into a monster.

Almost immediately he encounters problems when the lake where he is fishing is closed and tries his luck in the wilderness of Corbett National Park, sharing the territory with man-eating tigers and wild elephants.

To escape what appears to be the wrath of the gods, he travels to Thailand to a lake inhabited by sareng, as well as countless other introduced river monsters.

Despite not being a Hindu country, Thailand offers no protection from the gods as Jeremy seemingly catches every fish, especially red-tailed catfish, in the lake but the sareng.

Deciding to face his demons instead of running from them, he returns to India to take part in a Hindu blessing, to appease the gods and convince them he means the fish no harm.

"River Monsters Goes Tribal"- After gaining the tribe's trust, Jeremy lives his dream of reeling in a full-grown shark, with his bare hands.

"Mongolian Mauler" – Catching taimen in Mongolia is considered bad luck so Jeremy visited a shaman to appease the spirit of the river.

Featured animals: Anjumara, arapaima, flathead catfish, giant snakehead, grey reef shark, Nile tilapia, sockeye salmon Jeremy recounted some of his closest call with forces beyond his control that nearly turned danger into disaster.

"Rift Valley Killers" – Jeremy encounters crocodile and hippopotamus while helping the local fisherman tend their fishing nets for Nile tilapia.

Finally, he investigates the candiru-acù, a small catfish that dills holes in dead or dying animals before eating them from the inside.

After discovering countless fish in the lake bearing the signs of this ancient predator, he learns from a victim that the attacker is the sea lamprey.

Featured episodes: Jeremy revisits some of the many scientific projects he has worked with over his career and presents new information discovered since his time with the researchers.
