"In the city of Dallas, criminals are being pursued by the detectives of the homicide unit and then later, prosecuted by the district attorney. These are their stories."

LODlogo

Law & Order: Dallas is an American police procedural/legal drama series set in Dallas, Texas. Created and produced by Dick Wolf, the series premiered on NBC on September 2015 on Wednesdays at 8e/9c, as a follow-up to Law & Order: Special Victims Unit, which aired 7e/8c.

Set in Dallas, the series follows the same two part approach in the original series, but like SVU also will have significant development for the series characters. When a crime is committed, the victims are represented by two separate yet equally important groups: the Dallas Police Department, where a team of elite detectives and their ranking captain investigate the crime; and the Dallas District Attorney office, where the DA and his team of ADAs prosecute the offenders in trials. In almost every episode, the first half hour focuses on the investigation by the detectives, followed by the second half on the prosecution of the criminals by the district attorney. Both teams in the Dallas police and DA office work with the Medical Examiner’s Office, Crime Lab, psychiatrists, and other resources to help bring justice for the victims, and deliver it those that abuse it, Texas-style. Similar to the original series, some of the episodes will be "ripped from the headlines" or loosely based on a real crime that received media attention. At times a particular case could be longer and could take a season’s length to close.


UPDATED: Added episode summaries for the remainder of Season 10; added some spoilers for Season 11.
