Helena has died, but cannot move on. She is terrified of confronting the mistakes she made during her life as a veterinarian?terrified of meeting the souls of the hundreds of animals she?d euthanized, and terrified that her 37 years of life were meaningless, error-ridden, and forgettable. So Helena lingers, haunted by the life she left behind: David, her shattered attorney husband who, with Helena?s passing, has lost his one connection to a compassionate and heartfelt existence; her houseful of damaged but beloved animals, now bewildered without Helena?s presence; and her last project, Cindy, a chimpanzee who may hold the answers to the mysteries of human and animal consciousness and to Helena?s final release.
When Cindy is scheduled for a research experiment that will kill her, David suddenly must call upon everything he has learned from Helena to find a way to save Cindy. In the explosive trial that follows, Helena and David must confront their mistakes, grief, and loss? because the only way to save Cindy is to discover what it really means to be ?human.?
