In the wake of Muammar Gaddafi's demise, the Mediterranean's strategic waters become the stage for a new power play. Ali Hakim Sherif, emerging as Libya's formidable strongman, dreams of resurrecting the glory of the Ottoman Empire.

Together with Commander Jim Ward and an elite SEAL team, they are America's first line of defense, tasked with supporting Egypt against an audacious adversary. In a race against time, American forces face the daunting challenge of preventing a new empire's rise while protecting a centerpiece of global commerce.
