When a Mob boss is killed, his wife goes missing from the scene. The FBI and Jess look for the woman and $3 million in Treasury securities allegedly stolen by the dead man.
Jess and Brooke search for the brother of one of Alan's ex-partners. The partner is dying and needs a bone marrow transplant from her brother who has disappeared.
At the wedding of Eric's best friend, the groom is attacked and the bride goes missing. Tension increases between Brooke and Eric as Brooke investigates and Eric tries to protect his friend.
When a woman comes in reporting that she saw her brother who died 17 years ago, Brooke and Jess end up going up against the Army Criminal Investigation Division to find a former Special Forces soldier.
The baffling disappearance of a close acquaintance makes Brooke realise that a fiendishly clever serial killer, whom she was never able to prove guilty, has emerged from obscurity to resume his reign of terror.
