Mellingham's Chief of Police Joe Silva has his hands full when the Mellingham High School Class of 1969 holds their twenty-fifth reunion.
Not every member of the class is looking forward to the gathering. Eliot Keogh is returning to his hometown to find the person responsible for sending his father to prison on a false charge. Becka Chase, on the reunion committee, is distracted because the husband of her best friend Mindy, Vic Rabelard, is trying to revive their long-dead affair. She fears her husband will find out and leave her.
The reunion has barely begun when Mindy Rabelard disappears, and Vic is found near death, apparently the victim of some strange toxin. Chief Silva will have to travel back twenty-five years and fit together a series of interlocking events to figure out what's going on in the quiet coastal village of Mellingham.
