One Chicago has made NBC the place to be on Wednesday nights for shared-universe scripted drama. Unfortunately, Chicago Med, Chicago Fire, and Chicago P.D. are all taking March 11 off, so One Chicago fans will have to wait to find out what happens next on the three shows. There is some good news, though, as the shows are only taking one week off and will be back on March 18. Med will hit a milestone and P.D. and Fire will deliver their share of drama.

Read on to find out what's coming next in One Chicago with the March 18 episodes of Chicago P.D., Chicago Fire, and Chicago Med!

Chicago P.D. - "Before The Fall"

Chicago P.D. will seemingly take a break from the Upton/Halstead drama of the previous episode to put the cops of Intelligence on a dangerous case, which could result in lives lost. Admittedly, danger and death are hardly new to Chicago P.D., but Voight may need to tread lightly in "Before The Fall." Here's what's happening:

Voight enlists the help of a reformed gang member to get a key witness' testimony in a murder case. More lives are put on the line as a gang war brews.

P.D. has already run into some complications working with criminals in Season 7, and the trailer for "Before The Fall" proves Intelligence will be up against more than just bad guys. Apparently, Intelligence will clash with the Homicide division of CPD on a "high-profile case." Will lives be lost before the cops all manage to play nice? Find out on Wednesday, March 18 at 10 p.m. ET on NBC.

Chicago Fire - "Protect A Child"

Things will likely be a little lighter for Chicago Fire at 9 p.m. ET on March 18, but that doesn't mean the heroes of Firehouse 51 are in for an easy episode. Although the latest episode may have set Brett up for heartbreak, others will seemingly be in more danger this week:

Things get personal for Casey and Gallo in the aftermath of a suburban house fire involving a mother and her young son. Herrmann campaigns for more respect. Kidd has an idea for giving back to her community.

Things have gotten personal for Gallo a lot so far in Season 8 thanks to his tragic history, so it should be interesting to see what makes things personal for both him and Casey. Hermann has itched for more respect ever since his promotion, and Kidd has come a long way from running herself into the ground in the first half of the season. Interestingly, the promo for "Protect A Child" shows none of this, but rather Cruz in serious danger.

Chicago Med - "The Ghosts Of The Past"

And that brings us to Chicago Med, which opens the One Chicago block on March 18 at 8 p.m. ET by hitting its milestone 100th episode. With "The Ghosts Of The Past" taking Med to 100 shortly after Med (and the rest of One Chicago) scored a massive renewal, Med fans have a lot to be excited about. Here's what to expect in Episode 100:

Marking the series milestone 100th episode, Dr. Manning and Dr. Charles assist in a complicated case helping a 4-year old who they quickly learn is no stranger to the ED. Dr. Marcel and Dr. Choi tend to a police officer with a mysterious gunshot wound to the abdomen. Relationships are put to the test as secrets are revealed.

The description for "The Ghosts Of The Past" almost comes across as fitting for any old episode, although the last line suggests this could finally be the week when April comes clean to Ethan about her lingering feelings for Marcel. The trailer yields more clues about what's in store, which seemingly includes Will connecting even more with Hannah, Maggie and Ben tying the knot (or at least coming close), April suffering a health crisis (presumably due to rushing back into IVF), and Ethan looking betrayed as he cries.

Basically, don't miss One Chicago on Wednesday, March 18 unless you want to miss some serious drama on all three fronts! Catch Med's 100th episode at 8 p.m. ET, Fire at 9 p.m. ET, and P.D. at 10 p.m. ET, all on NBC.
