On an island marina off the Florida coast, Elizabeth works to communicate with a killer whale. No one else has ever had an opportunity like this - no whale has ever voluntarily come in from the wild before. Then one day the whale speaks. But can humans accept this urgent approach from another species? Or will the whale be dismissed as a freak?
Beyond the marina, nuclear and biological disaster loom. Inside it, Elizabeth's loyalties are stretched to breaking point as she clashes with management, clashes with on-off boyfriend Joe, fights to continue her work, and fights to understand why the whale has made this sacrifice. And why now?
Inspired by a childhood dream, she uses advanced technology to overcome the limits of language and rediscover the ancient kinship between land and sea.
