Deep in the heart of Africa, a killer is on the loose.

Over a period of 10 years, nearly 300 people in the vicinity of Burundi's Lake Tanganyika have disappeared. Initially thought to be the result of tribal warfare or the work of a serial killer, the disappearances are now being attributed to the largest Nile crocodile ever seen - nearly 30 feet long - and almost a century old.

Capturing the Killer Croc follows a team of scientists in a race against time to apprehend the giant crocodile before he kills again.
