Investigates the greatest vanishing act in the history of our planet - the sudden disappearance of the dinosaurs 66 million years ago. Experts suspect that the dinosaurs were wiped out after a city-sized asteroid smashed into the Gulf of Mexico causing a huge crater. But until now, they haven't had any proof. In a world first, evolutionary biologist Ben Garrod joins a multi-million pound drilling expedition into the exact spot the asteroid hit to get hard evidence of the link. The team overcomes huge obstacles as it attempts to drill 1,500 metres beneath sea level to pull up rock from the Chicxulub crater.

The undercover cameras reveal how animals rely upon each other for a range of activities. Arctic wolves group together to survive in one of the harshest landscapes on earth, a band of hungry mongoose groom warthogs for tasty morsels - before turning their attention to Spy Warthog - and fish help clean hippos' bodies, as well as providing a unique dental service. Meanwhile, crocodiles and dikkop birds take part in a mutual neighbourhood watch against hungry prowling monitor lizards, and Spy Rattlesnake captures how prairie dogs and burrowing owls use their language skills to tell the rest of their community of approaching danger.

In some of the world's most spectacular natural wonders, people push themselves to the limit in order to survive. For the people who call these extraordinary places home, survival requires skill, ingenuity and bravery. In Brazil, the Kamayura people of the Xingu Indigenous Park believe they must appease the spirits if they are to remain in good health. In Ethiopia, belief in a higher power leads villagers in the Tigray region to climb a huge, vertiginous mountainside to reach their church. Laos is one of the most fertile places on earth. Despite this, life is dangerous for the rice farmers in this beautiful country. During the Vietnam War, the United States dropped an estimated 270 million bombs on this small country and approximately 80 million of them failed to explode.
