Early one morning, two FBI agents, Portman and Cross, visit the Peterson home. Jack Peterson, a young psychology professor, had just inherited the house from his grandfather in addition to various other investments and businesses before marrying his newly pregnant wife, Anne. Portman and Cross question Jack concerning the murder of two young women and ask to see his handgun. Jack denies knowing or ever meeting the women, but admits to losing the gun years ago.

The FBI continue to investigate Peterson’s past, but he continues to deny any involvement. Anne, Jack’s wife, happens upon the “lost” handgun in a box from the basement. This discovery builds tension and distrust between the couple and Jack assures her he will bring the gun to the FBI. Jack’s escalating strange behavior raises not only the concerns of his wife, but also the FBI, who are watching him constantly.

As more things about his past start to unravel we find out that the suicide of his twin brother, Jimmy, brought on by post-traumatic-stress-disorder, led to Jack’s creation of a drug formula. Does this formula have anything to do with the dead women? Is he being framed by a pharmaceutical giant or is Jack really a murderer? What develops is a story driven not just by the characters discovering clues to Jack’s past, but also the relationships of those around Jack Peterson and the tight knit community of Greenville, Maine.
