For a decade, a network of cameras hidden deep in Montana’s Sapphire Mountains has been watching. The result is an unprecedented and intimate look into the secret life of a creature that lives to remain unseen. This film pieces together the complete life story of Willow, a female mountain lion, and her young.
Using only footage captured by these non-invasive trail cams, the episode constructs a gripping narrative of survival. Every frame reveals the complex social interactions, the life-and-death hunts, and the maternal bonds that define Willow’s world. This is a biography of a ghost of the forest, told entirely in her own actions. How does a mother teach her kittens to survive in a world of constant threat, and what never-before-seen behaviors are finally brought into the light?
Nature airs Wednesday October 29, at 8/7c on PBS.
