The investigation into the death of Caleb Shimansky, a bike messenger, takes a personal turn for Beckett and her colleagues when they discover that the victim was carrying evidence that could exonerate Brady Thompson, a man jailed years before by Captain Roy Montgomery for the murder of Olivia Debiasse. Things get even more interesting when they discover that a wealthy candidate for the U.S. Senate from a prominent New York family may have been involved as well.
