What order should I watch Chicago Fire, PD and Med?

One Chicago is one of the most exciting franchises in all of television. They depict varying aspects of the big city, and sometimes they even crossover with one another in an attempt to show how policemen, firefighters, and doctors can band together for the greater good.

That being said, these crossover events can sometimes make the viewing of these three shows confusing. There are stories that appear unfinished if you watch them out of order, or allusions to events that you may not know about if you don’t keep up with one of the other titles.

Here’s a rundown on the best order to watch Chicago Fire, PD and Med.

Chicago Fire is the best possible starting point for newcomers. It was the first show to debut back in 2012, and oftentimes serves as the catalyst for larger stories involving PD and Med. In fact, PD was given a backdoor pilot in the Chicago Fire episode “Let Her Go”, which introduced viewers to Voight (Jason Beghe) and the rest of the IU. Fire also worked a backdoor pilot for Med into season 3 with the episode “I Am the Apocalypse”.

The chronology of all three shows is pretty easy to follow for the most part, with time moving at a relatively normal pace. That is, until you get to the crossovers. The first major crossover in the One Chicago universe takes place in 2014, with the Chicago Fire episode “A Dark Day” rolling right into the Chicago PD episode “8:30 PM”.

These episodes introduce and wrap up a case over the course of its two episodes, but if you were to only watch the Fire or PD episode you would only get half the story. This crossover format has become commonplace for One Chicago, with dozens of two and three-part crossovers being told over the last few years.

The most recent, and perhaps the most notable, is the three-part episode “Infection.” The story, which involves a virus spreading throughout the Windy City, played out over a single night on Fire, Med and PD. Watching each show on its own via streaming would be incredibly confusing, as each show carries a crucial piece of the puzzle.

As a general rule of thumb, you can watch the One Chicago shows in order, except for when they engage in crossover episodes. Then be sure to track each show and episode title to make sure you get the entire story.

Chicago Fire showrunner Derek Haas has hinted at more crossover plans for the future, so there will be even more chances to practice this new viewing habit in real time!
