For many long years, Atlee Pine was tormented by uncertainty after her twin sister, Mercy, was abducted at the age of six and never seen again.

With time running out, Atlee and her assistant Carol Blum race to Vincenzo's last known location in Trenton, New Jersey -- and unknowingly stumble straight into John Puller's case, blowing his arrest during a drug ring investigation involving a military installation.
