The trio investigates the deaths of a teenager and a car salesman whose brains have been liquefied after watching a video sent to their computers. All of the victims are connected to a computer programmer (Chris Bauer) who has lost his job. The murderer then sends the video to Olivia's laptop, almost killing her niece Ella, before Olivia is able to intervene. In order to catch the suspect, Olivia defies an order from Agent Harris, and Broyles puts his friendship with Harris on the line to defend her.
