A handsome and successful young man with a lovely fiancée, James Jackson seems to have everything going for him, but his life begins to unravel when he develops an acute sense of paranoia. At first, he notices little things at his office that he takes as signs that people are out to get him, but soon things escalate, with Jackson convinced that a perfume ad on television holds sinister messages aimed at him. Is Jackson losing his mind, or are the threats real?

The third installment of the “Law & Order” franchise takes viewers deep into the minds of its criminals while following the intense psychological approaches the Major Case Squad uses to solve its crimes.

In cases ripped from the headlines, police investigate serious and often deadly crimes, weighing the evidence and questioning the suspects until someone is taken into custody. The district attorney's office then builds a case to convict the perpetrator by proving the person guilty beyond a reasonable doubt. Working together, these expert teams navigate all sides of the complex criminal justice system to make New York a safer place.
