Jesse Cardoza returns to Miami and the Crime Lab just as a masked man takes it over. The man, calling himself Ted, takes Jesse, the receptionist and two lab techs hostage, asking only to speak to Horatio Caine. When Caine gets there, Ted tells him that he wants justice. He shoots the receptionist and Horatio gets in there and takes her out, discovering that Jesse is there. Matthew directs him to a check cashing place where they should get $100,000 dollars for him. They do so but this turns out to only be a clue from Ted as to the justice he wants. The money is counterfeit and the owner of the check cashing place, Darren Ripley, used to be his business partner and completely bankrupted him and ruined his marriage. The owner identifies Ted as really Matthew Sloan. When he calls Horatio to check up on the fate of Darren, he tells Horatio that he's not finished with getting justice. They discover he's going after his ex-wife, now remarried as Rebecca Arrington. The CSIs remove her, her son and new husband only to find that Matthew still breaks into their house but leaves immediately. Or so they think. Upon investigation, they discover that Rebecca's new husband was actually the one to break down the door to frame Matthew. Jesse also discovers that Matthew lost his son due to accusations of child abuse but they probe and find out, Rebecca was responsible for it. Horatio arrests both Rebecca and her husband and reunites Matthew with his son for one moment before he as well gets taken into custody. Horatio got justice once again.­
