There's something wrong at the Pacific Institute...something wrong and evil. For young Mari, whose family has worked in the finishing industry for generations, her studies in advanced genetics and marine bio-engineering represent not just her own future, but that of her entire family. But when her friend Nanako is mysteriously discovered dead, Mari's dreams turn into her worst nightmares! Because not only was Nanako's body covered with fishbites, she was also growing scales! Now, as a new wave of deaths and tragedies engulf the Pacific team, it becomes all too clear that someone....something...has a new future in mind for all human kind. For centuries man has taken from the ocean, never dreaming what might lurk beneath the waves; now the revelation has begun...and this time, we're the sushi!
