The dynamics are simple in the Wolf family. They eat you if you let them. Joe Wolf has raised three sons and one daughter using the same cut-throat mentality that built his California business empire- Kill or be killed. So when he is found murdered on his yacht adrift in San Francisco Bay, SFPD detective Ben Cantor knows exactly where to begin his investigation. As the siblings vie for control of their father's vast power and assets, the detective pieces together the hierarchy of the 'pack of wolves'. All four have the means and the motive to commit murder. Meanwhile, a more sinister player lurks in the shadows, one who knows the Wolfs' secrets better than Cantor ever will. And who wants them all dead.
