After decades of marriage, a wife looks at her husband and sees, "A man in longing. For what I couldn't have said." As she follows him into Yellowstone National Park and deep into his burgeoning obsession with the wild, she struggles to find the right balance between supporting and enabling what seems more and more to be her husband's desire to become a member of a wolf pack. A fascinating look at isolation and connection in all its forms - between generations, between species, and even between people who have shared a lifetime side by side.
