I’m not really recommending this – just noting what is a very rare TV event. Tonight, NBC presents three different one-hour dramas all telling the same sequential story. It begins on Chicago Fire with an episode about an investigation that brings to town Sgt. Benson (Mariska Hargitay) from Law & Order: Special Victims Unit. The story continues at 9 ET on a new episode of Chicago P.D., an NBC drama series also executive produced by Dick Wolf. Finally, it concludes at 10 ET on Law & Order: Special Victims Unit, one of Wolf's earliest, and still running, series. Wolf did two-show crossover story lines as far back as on the original Law & Order and a show he didn’t create or produce, Homicide: Life on the Street, which is where the character of Richard Belzer’s Munch originated. But three shows? That takes some logistical planning.
