Episode 3 - Killer Snakehead
Angler Jeremy Wade sets his sights on an aggressive Far Eastern predator that's now invading America's backyards. Accused of homicide, and said to breathe air and crawl on land, the Snakehead is a monster that sounds more like a gangster than a fish. Does its bite match the hype?
Episode 4 - Congo Killer
Jeremy Wade travels to one of the few rivers left on earth that will still test a fisherman. The Congo, a river steeped in legends, and soaked in violence. One spirit in particular is said to lure fishermen from their boats to their death. Jeremy discovers that the truth is every bit as frightening as the myth.

Episode 6 - Rift Valley Killer

Episode 7 - Hidden Predator
Bull sharks are the most aggressive and unpredictable of all the sharks and thought to be responsible for more attacks on people than any other. Last year the biggest bull shark ever recorded was caught in a river in South Africa.
Jeremy Wade travels to this river to see if last year's catch was a one off or if there are more monsters out there, and discover if the presence of this known man-eater is a human tragedy just waiting to happen.
