It's death on an unimaginable scale, when a majority of Earth's species quickly die out. It's called "mass extinction," and it's happened at least five times before. Cataclysms, such as supervolcanoes or asteroids, are thought to cause these events, but some experts believe a man-made mass extinction could be next. Is our planet in trouble? And if so, is there anything we can do to stop the next catastrophic annihilation? Experts are traveling the world, performing groundbreaking scientific detective work to answer these very questions.

Liz meets the animal rebels who will stop at nothing to survive. From cockatoos vandalising houses in Sydney, to crabs who hold nemones hostage to protect themselves, it seems there are no lengths these animals won't go to. Liz sets out to see these animals in action, revealing the science behind their extreme behaviours. She meets the sloth whose disgusting hygiene habits may help hide it from predators, the stone martens who cause millions of pounds' worth of damage to cars to protect their territories and the chimpanzees who use bullying tactics to get to the top. As Liz discovers, when life in the wild gets tough, this outrageous behaviour could just be the key to survival.

The next programme deals with flying insects. It begins in Central Europe, where the Körös River plays host to millions of giant mayflies as they rise from their larval skins to mate. — the climax of their lives. Mayflies and dragonflies were among the first to take to the air about 320 million years ago, and fossils reveal that some were similar in size to a seagull. Damselflies are also looked at in detail.
