But calm waters begin to stir as an offshore drilling protest turns into a terrorist hijacking. When the hijackers reveal part of their elaborate scheme, Dixon suspects foul play. With the help of FBI Agent Lisa Reed coordinating the counter-attack from shore, it's sink or swim as Dixon and Reed try to save the hostages, but can they diffuse the deadly plan before it's too late?
