Chicago Fire season 12 plot

Here's an overall synopsis of the series from NBC:

"From renowned Emmy Award-winning executive producer Dick Wolf (Law & Order brand) and co-creator Derek Haas, the writer behind 3:10 to Yuma, comes the adrenaline-fueled drama Chicago Fire. This edge-of-your-seat ride is a look into the professional and personal lives of the firefighters and paramedics of Firehouse 51 as they risk their lives every day to save and protect the citizens of Chicago."

Chicago Fire season 12 cast

Kara Killmer announced in mid-November that she will be wrapping up her run as Sylvie Brett in season 12. It's unclear how many episodes of season 12 she will appear in, but it looks like Sylvie might be accepting the marriage proposal from Matt Casey (Jesse Spencer, who left the show in season 10). Spencer returned in season 11 when Kinney stepped away, making several guest appearances and ending the season by popping the question. Since his character lives in Oregon, it would be a natural way for Sylvie to leave while also leaving the door open for a potential return. 

Alberto Rosende will also depart the series in season 12. According to Deadline, his final appearance will take place in the season premiere. 

Here's who we expect to see in the upcoming season: 

 

  • Eamonn Walker as Deputy District Chief Wallace Boden 
  • Taylor Kinney as Kelly Severide
  • Kara Killmer as Sylvie Brett 
  • David Eigenberg as Lt. Christopher Herrmann 
  • Miranda Rae Mayo as Stella Kidd
  • Joe Minoso as Joe Cruz
  • Christian Stolte as Randy “Mouch” McHolland 
  • Daniel Kyri as Darren Ritter
  • Alberto Rosende as Blake Gallo
  • Hanako Greensmith as Violet Mikami 
  • Jake Lockett as Sam Carver
