Chicago Fire

NBC | 9:00 pm

Fans of this ensemble drama may want to brace themselves for the Season 8 premiere, which showrunner Derek Haas cautions is "as brutal as we’ve done" and is only a prologue to some lingering fallout. Back together, Stella and Severide (Miranda Mayo, Taylor Kinney) offer strong support to each other during this trying period, and Casey (Jesse Spencer) is too distracted to obsess over Brett’s (Kara Killmer) unexpected engagement to Chaplain Kyle Sheffield (Teddy Sears).
