When the Chicago-based NBC shows return in 2017, a dramatic crossover is going to ensure that a story connects characters from “Chicago Fire,” “Chicago Med” and “Chicago P.D.” With the winter premiere of all Dick Wolf-created shows slated to air next week, here is everything we know about them:

1. “Chicago Fire”

The “Fire” and “P.D.” crossover will see Severide go into crisis mode after receiving some bad news about his bone marrow donation, TVGuide reports. Things get worse for the firefighter when he is arrested for a crime he didn’t commit. His ex-lover, Detective Erin Lindsay (Sophia Bush), appears to help her old flame. She, Voight (Jason Beghe) and their team need to prove his innocence.

Meanwhile, Casey (Jesse Spencer) and Dawson (Monica Raymund) will have to deal with Louie’s father suddenly appearing in their lives. However, things get even more complicated for the new parents in the Jan. 3 crossover episode. Also, when he is on call, Casey will have to make a split-second decision about who to save which will have some serious repercussions.

2. “Chicago P.D.”

Lindsay will meet her absentee father in the Jan. 4 crossover episode, but his motives for suddenly reconnecting with her aren’t clear. Secrets will be revealed and the Detective’s relationship with her mother will get worse as a result of learning the truth.

Meanwhile, the newly promoted Burgess (Marina Squerciati) is going to find it hard to transition to Intelligence. Her ex-fiancé Ruzek (Patrick John Flueger) isn’t very supportive of her new career move.

3. “Chicago Med”

Dr. Natalie Manning (Torrey DeVitto) will lose a patient in the Season 2 midseason premiere. Due to this, she will be reviewed. A routine inquiry will be launched where she will be put on trial. As a result, Manning will feel like she is on the hot seat, according to the NBC series’ co-executive producer, Andrew Schneider.

Elsewhere, dark times are ahead for Nurse April (Yaya DaCosta), who discovered that her tuberculosis medicine will affect her unborn baby’s growth. Whether she and Tate will overcome this problem remains to be seen. “She will take the treatment [for TB], but ... Her cure could be affecting her baby,” co-showrunner of “Chicago Med,” Diane Frolov, said. “It poisons [the relationship]. It’s very, very trying for them.”

“Chicago Fire,” “Chicago P.D.” and “Chicago Med” return with a crossover episode on Tuesday, Jan. 3 at 9 p.m. EST on NBC. “Chicago P.D.” continues the crossover on Wednesday, Jan. 4 at 10 p.m. Finally, “Chicago Med” ends the #OneChicago episodes on Thursday, Jan. 5 at 9 p.m. EST.
