Gabe and Marla Easton move to Hatteras Island on North Carolina's Outer Banks to escape from a stress-filled world in hope of conceiving their first child. Shortly after their arrival, a brutal rape/murder occurs on the island. As the investigation proceeds, the Eastons are drawn into the search for the killer. Soon, everybody seems to exhibit suspicious behavior.
A trail of bodies from Frisco to Nags Head, North Carolina, leads Deputy Easton and Sheriff Walton to the discovery of the Methuselah serum - a new drug designed by Hopkins that reverses aging in human cells. A nefarious triumvirate of pharmaceutical CEOs known as "the Medical Mafia" wants the formula at any price. So do the FBI and the President of the United States. But Sheriff Walton believes that he and Deputy Easton have been divinely chosen to guard the formula and serum.
