NBC Sets CHICAGO FIRE, CHICAGO P.D. & LAW & ORDER: SVU Three-Part Crossover

Dick Wolf's Universal Television/NBC series "Chicago Fire," "Chicago P.D." and "Law & Order: SVU" will be united during a major three-part crossover airing Nov. 11-12.

The three series will share a storyline about a child pornography ring that stretches from Chicago to New York and will arc over three episodes, beginning with "Chicago Fire" (Tuesday, Nov. 11, 10 p.m. ET/PT) and continuing on "Law & Order: SVU" and "Chicago P.D." (Wednesday, Nov. 12, 9 and 10 p.m., respectively).

"Warren Leight ("SVU" showrunner) and Matt Olmstead ("Chicago Fire"/"Chicago P.D." showrunner) are two of the best writers in the business. We wanted to figure out a way to create a crime that connects all three shows. Warren, Matt and I came up with a story that was big and unique enough to transit to all three," Wolf explained.

"Chicago P.D." followed with a 1.9/6 in 18-49 and 8.5 million viewers overall to win THE HOUR among ABC, CBS and NBC in total viewers with the show's biggest overall audience since its series premiere on Jan. 8.

All three shows are produced by Wolf Films in association with Universal Television.
