Sophie is joined in the theatre by chirping crickets, hissing cockroaches and groaning deer to reveal the very different ways that animals have adapted their bodies to send audible messages that are vital to their species. She also explores how and why the human voice evolved to become the most versatile sound producer in the natural world. She demonstrates what sound actually is and how it travels. Unpacking the power behind sound, she uses it to shatter glass and reveal how the human body can resonate in a way that amplifies our voices to send our messages further. She also explores how different species use very different frequencies to communicate and why humans can only hear a fraction of these animal messages. Finally, she investigates why we all have unique vocal prints, and how computers are learning to recognise these.

This programme surveys mammal herbivores and their predators. The herbivores began to populate the forests when the dinosaurs disappeared, and many took to gathering food at night. To prepare for winter, some store it in vast quantities, some hibernate and others make do as best they can. However, the carnivores joined them, and when a drying climate triggered the spread of grass, they followed their prey out on to the plains. Grass is not easily digestible and most animals that eat it have to regurgitate it and chew the cud. Out in the open, the leaf-eaters had to develop means of protection.
