David Attenborough, World renowned English naturalist, explores the life of Jumbo. This African elephant arrived at London Zoo in 1865 as a part of a ploy to bring exciting new creatures to the park which would inspire the masses. He was a gentle giant by day, but by night he would have fits of rage, often smashing up his cage. Attenborough and a team of scientists hope to unravel the reason for this and the death of Jumbo with unique access to the elephants remains.
