Given the opportunity, would you assume someone else's identity and leave your old life behind?

A serendipitous crossing of paths between Lisa Barnes, a down-on-her-luck job seeker, and Julie Forman, a personal trainer to an Olympic hopeful, forever changes the course of both women's lives.

One winds up dead and the other finds herself a fugitive, hiding behind lies as a cold-blooded killer methodically hunts her. Desperately trying to stay alive, the terrified woman enlists the help of Forensic Instincts, a rogue investigative team that clandestinely operates in the gray area between legal and illegal. Safeguarding their client's deception, Forensic Instincts digs into dangerous territory as they try to find out who's after their client and why. Meanwhile, bodies are piling up in Chicago, New Jersey, and Vermont as a megalomaniacal genius will stop at nothing to eradicate anyone who threatens the success of his medical breakthrough.

With an unhinged client and a monstrous criminal enterprise as its adversary, Forensic Instincts is forced into uncharted territory to protect their client and save one of their own from becoming the next corpse.
