When a bookkeeper goes missing, Goren and Eames are led back to the death of her brother, a hitman, two years earlier. An imprisoned mobster seems to be their best bet, but when another body turns up it takes the case to a whole new level.

While tracking a modern-day Bonnie and Clyde (Rodney Hicks and Nikki M. James), Goren deduces that one of his suspects has an injured foot. It isn't long before Goren and Bishop realize the pair, who have already killed nine people including two undercover cops, are not the typical Bonnie and Clyde – the female partner is obviously the one in control.
