Steve Backshall travels to Indonesia in search of three very different reptiles to add to his list of 60 deadly predators. He and his crew have a nerve-racking close encounter, when they are chased by a group of ravenous, three metre long Komodo dragons, the world's largest venomous lizards. Steve also demonstrates the incredible gliding technique of a tiny flying lizard and heads out on a nocturnal hunt for the beautiful but lethal green pit viper.

In the medieval Ethiopian city of Harar, Steve Backshall has a unique and potentially lethal encounter with a pack of spotted Hyenas. Capable of tearing their prey apart with super strong jaws and thick muscular bodies, here they are hand fed, allowing Steve the encounter of a lifetime with this normally unapproachable predator. Out of the town and up into the Mountains Steve meets the rarest wolf on earth and discovers why a grass-munching monkey, the Gelada baboon, has a set of teeth that would make a vampire jealous.

This time on Deadly 60 Steve's on his home turf, scouring land, sea and air, for some of the deadliest critters that the UK has to offer. First, he heads for the seas off the coast of Plymouth, in search of monsters from the deep.

Adventurer Steve Backshall and the Deadly 60 team pack their cold weather gear and head north to Alaska. They battle for days and nights in the freezing conditions of the frozen tundra, hoping to find polar bears to add to the list. They are rewarded with a rare sighting of a wolverine and some cheeky Arctic foxes. Steve looks for the place where thousands of bald eagles arrive every year to feed on the spawning salmon.

Steve gets close to a great white shark.

Deadly 60 are in Mexico.

The wildlife action moves to the south coast of Australia as naturalist Steve Backshall and the Deadly 60 team take the plunge in the waters of the Pacific. Steve has heard that yellowfin tuna are super-fast lethal killers, but what makes them so special? Strange alien-like giant cuttlefish also await Steve in the warm Pacific waters. It is then a short hop up the coast to try and track down perhaps one of the weirdest animals on Steve's list, the elusive duck-billed platypus.

Steve and the team head to New Zealand for the first time. Steve descends deep into the Waitomo caves to find an unusual predator that lures insects to their death with a lethal lightshow, the glow-worm. Then he heads to South island, to get an aerial view of one of the biggest animals on Earth, the sperm whale; before driving inland to meet a very curious bird armed with deadly intelligence. Finally, Steve returns to the ocean in search of sperm whales and uses his kayak to get an awe-inspiring close-up view.

Steve Backshall plays football with cheetahs, learns about the hunting techniques of crowned eagles and films three lethal snakes - a cobra, a boomslang and a puff adder.
