Chris Packham examines some of the weirdest natural events on the planet. With the help of footage taken by eyewitnesses and news crews, he unravels the facts behind each story. In the first programme, there is the mysterious case of the car cocooned by caterpillars in Holland, and the baffling case of the exploding toads in Germany. In Switzerland a lakeside town is entombed in ice and a once in a lifetime storm turns Sydney, Australia crimson overnight. There are some disturbing plagues of mice and locusts and a swarm of ladybirds. And finally there are extraordinary strandings of starfish, crabs and whales.

Chris tells the real story of the events behind the headlines and helps to explain what on earth happened.
