A woman, Lindsay Bynum, is escorted out of her maximum security prison cell, and promptly vanishes once she is departs out the main gate. The agents learn that this formerly successful financial advisor got caught in a downward spiral that led to an embezzlement conviction. Released the month before, she had been visiting a friend in prison on the day of disappearance. When Jack and the team arrive on the scene of an auto accident, they find Lindsay's car smashed up at the roadside. A second set of tire tracks and footprints lead them to speculate: was this recently released prisoner the victim of an opportunistic passerby or did something from Lindsay's prison life follow her outside?
Her two children, abandoned by their father when he committed suicide soon after Lindsay's imprisonment, were taken in by Lindsay's brother-in-law and wife, Jake and Natalie. The case takes a turn when they learn that Lindsay had discovered that her youngest son, Ryan, was stealing. She may have involved herself in a dangerous scam to buy him out of his debt. Ryan eventually confesses that Lindsay tried to save Ryan from the bad situation, and Ryan accidentally hit her while driving a truck. She's dead, and he reveals the location of her body.
Meanwhile, Vivian and Mars continue their search for the victims of a sex slavery ring. An ambitious raid on a brothel gets them closer than they think to the trafficking ringleader.
