Near future. World-renowned mathematician/physicist Francis Dullam loses his left brain hemisphere and retires from the hard science to study dolphins. Several years later he comes up with a new thesis (which is essentially a collection of dolphin footage). As the "thesis" is being severely criticized by the media, Ishii Mitsunari (a student living in America) discovers the idea hidden there, that will help create a true Artificial Intelligence. Motivated to create the AI first, Mitsunari leaves for Okinawa, to follow the footsteps of Dullam.
