Croc Labyrinth

Two divers make unprecedented discoveries deep within the lair of the Nile crocodile. Herpetologist Vince Shacks and underwater cameraman Brad Bestelink go on a unique crocodile diving adventure in Botswana's crocodile-infested Okavango delta to find out more about these cave systems, and how the reptiles use them. They enter a dark underworld of mystery and danger, and they find themselves doing things that no human has ever attempted before.
