Former Army Ranger Jake Spinner spends most of his days in a tequila-induced fog. Between bouts of binge drinking and episodes of PTSD, he works as a fishing guide in a sleepy village in Baja California, Mexico.
After the body of Spinner's estranged fishing partner washes up on the rocks, he becomes obsessed with finding his friend's murderers. His search leads him to a reluctant alliance with Emily Rosen, a feisty New York Times reporter, and a team of marine biologists. They have discovered an illegal Japanese dolphin hunt and whaling operation run by the yakuza, vicious criminals who will stop at nothing to harvest these valuable marine mammals.
Outnumbered and outgunned, Spinner, Rosen, and an unlikely assemblage of scientists, activists, and fishermen must come up with a plan to stop the impending slaughter--without getting themselves killed in the process.
