Elephants can live for 70 years. But what happens when one of these magnificent beasts dies in the wild? This film turns normal wildlife documentaries on their head to find out what happens after death, as a five-tonne adult elephant is transformed into six million calories worth of fat, meat and guts, feeding a whole new cycle of life. The documentary gives scientists the chance to watch close up, day and night, as animals from leopards, hyenas and vultures to flies and beetles take just days to reduce the largest land animal on earth to bare bones. Biologist Simon Watt leads a team of experts watching the events unfold in Tsavo West National Park in Kenya. If that's enough to put you off yer dinner, you might prefer to observe the new series of Masterchef, which starts on BBC1 at 9.00pm.
