NBC ’s government-employee dramas Chicago Fire, Chicago P.D. and Law & Order: SVU are set get down and dirty with each other in a three-episode, three-part, three-show crossover the likes of which we’ve seen a few times before. The story will focus on a child pornography ring that spans both New York City and Chicago, prompting our heroes to join forces—and quickly deflating any additional sex jokes about the crossover.

Producer Dick Wolf has a hand in all three shows—Chicago Fire and Chicago P.D. are in their third and second seasons, respectively, while SVU just started its 16th season. To watch the entire crossover, viewers will have to start with Chicago Fire on Tuesday, November 11, at 10 p.m., followed by SVU at 9 p.m. and Chicago P.D. at 10 p.m. on Wednesday, November 12.
