Everything We Know About This Year's One Chicago Crossover So Far

Chicago Fire and Chicago P.D. bosses dish on the epic event

Keisha Hatchett

This year's major crossover between Chicago Fire, Chicago P.D.and presumably Chicago Med, expected to air in early March, promises to be more involved than ever. With Chicago P.D. celebrating its 100th episode during the major event, the stakes will be high and call for a greater collaboration between the shows.

The crossover, which will begin on Wednesday night with Chicago P.D. and then finish out with Chicago Fire on Thursday, will see Dawson (Monica Raymund) and Brett (Kara Killmer) trading in their EMT hats for some undercover action with Chicago P.D.'s Central Intelligence crew. After saving a heart attack victim, Antonio (Jon Seda) will enlist them to help with a case regarding said person.

"Antonio comes to the firehouse and asks Boden (Eamonn Walker) [to use them] in their roles as paramedics to distract this guy so [Central Intelligence] can slip into their house," Chicago Fire showrunner Derek Haas tells TV Guide. It's a break from traditional crossover episodes which usually features one show handing off the case to another. This time around, you can expect to see even more overlap than before.

And much like last year's "Deathtrap," which centered on deadly warehouse fire mirroring the Ghost Ship warehouse tragedy in Oakland in December 2016, this year's two-episode event will also be topical. Taking on fake news, the story will center around the idea of new media versus old.

"It'll focus on a man whose life has been essentially destroyed by social media," Chicago P.D. boss Rick Eid explains. Described as a "real journalist," he'll seek revenge on someone who apparently has been spreading lies about him. "It's a real journalist who played by the rules, who checked his sources and vetted the facts, [and] is on the wrong end of a social media smear campaign."

The major crossover event is expected to air in early March. In the meantime, catch Chicago P.D. on Wednesdays at 10/9c, and Chicago Fire on Thursdays at 10/9c on NBC.
