Coast Guard investigators Rissi Dawson and Mason Rogers are out to investigate the events that led to an accident claiming the life of an oil-rig worker on the first drilling platform off the North Carolina coast. Tensions surrounding the oil rig are already high, and the death puts everyone on edge. Environmental activists are willing to do anything to stop the structure from being completed, while rumors spread about ancient curses surrounding this part of the ocean.
Mounting evidence reveals the death may not have been an accident at all. Was he killed by an activist, or worse, a member of his own crew? Rissi and Mason have to sort through, not only a slew of suspects, but also their own past and attraction to each other.
Just as the case looks like it'll break open, even worse news arrives. A tropical storm is turning their way, and soon they will be cut off from rescue, right where the killer wants them. It's a race to uncover his identity before he eliminates the threat they pose.
