The novel opens with an impending world-wide telecast of the first inter-species communication in the history of the world. Humans will be conversing with dolphins during a global television broadcast. As the first few chapters unfold we learn about Dr. Robert Mornay, a specialist in Marine Biology, who discovered this secret of how dolphins communicate: They Speak Pictures. As Mornay watches the introductory material of the broadcast, he reminisces over his childhood as he grew up reading all of the Dr. Doolittle books in his local library. We learn about how he discovers the secrets of dolphin communication during the breakup of his first marriage and his subsequent divorce and re-marriage.
At the end of each chapter the Dolphin People speak to the Human People in the form of pictures, moving pictures, newsreels of history, with dialogue in each country's native language provided by the simultaneous translation of the visual dolphin language into words.
The material in the novel about the possibilities of dolphin communication is within the realm of scientific possibility using available neural net and virtual reality technology.
