Christian Roberts, a handsome, young Floridian, has retired from horse racing and sets off with his wife, Allie, to cruise the Caribbean on his new sloop. Tragedy strikes, ending the dream vacation, and Christian becomes the prime suspect in a murder.
Shattered and guilt ridden, Christian believes his actions caused the death, and suicide lurks in his thoughts, a way to end his pain, but he can't act on the impulse, at least not yet. He must honor a dying request: “Save the sharks. Do it for me.”
Christian embraces the impossible task of stopping the shark slaughter. Under the alias of Captain Nemo, he becomes an eco-terrorist while a suspicious FBI agent dogs his every move. Will Christian be caught and imprisoned? Will the fin traders kill him? Could despair win out, causing him to take his own life? Or will Christian succeed and save the sharks?
