Nature documentary. Australia's deadly saltwater crocodiles are making a dramatic comeback, spreading in alarming numbers through the billabongs, rivers and beaches of the Northwest Territories.

Last year over three hundred crocodiles had to be removed from the harbour of Darwin, the region's capital. Thousands of cattle are being killed and, most worryingly of all, attacks on people are increasing every year - often in places where crocs were previously unknown.

Biologist Adam Britton is trying to find out why the crocs have suddenly become such a problem. With satellite transmitters he starts to monitor their movements, and the results are startling. As the problems mount, and with desperate locals clamoring for a cull, Adam urgently needs answers.
