Leopards are the ultimate cats. They are the most feline, the most intelligent, the most dangerous and, until recently, one of the least understood. They hunt from South Africa to Siberia, from Arabia to Sri Lanka, and are the most widespread predator of their size on land. A leopard is a cat that walks by itself, unseen and secretive. Leopards are the beautiful killers that live in the shadows. This film will accumulate the evidence and put together a psychological profile of this extraordinarily cunning cat.
