"Chicago Fire" is famous for its plot twists and investigative skills that centers on the team at Firehouse 51. There is no lack of drama surrounding these fearsome firefighters, and certainly none after Chief Boden left.

In episode 17 of season three, named "Forgive You Anything", Lt. Severide asks Chief Boden for a favor for Scott Rice who is an old friend seeking a second chance with the Chicago Fire Department, reports Cinema Blaze. While Severide seems confident, Casey and Otis harbor doubts. In other news, Mills will work to regain his active squad status while Brett and Dawson decide to have a big night out. TVGuide reports that Mouch confronts his fear about meeting his child. He is, after all, meeting his biological child for the first time after giving a donation at a fertility clinic.

Perhaps the most shocking aspect of the episode is that the firehouse would be confronted with a drive-by attack. A sneak peek video reveals that a number of people will be sprawled on the sidewalk after being run-over. It seems that there isn't a specific reason why it happened, but a reason will be uncovered soon enough.

Obviously, the attack leads to firefighters and paramedics arriving on scene and dealing with the situation. The issue is investigated, as is always the case in any situation Firehouse 51 deals with. They strive to get to the bottom of the issue. This is certainly a dire situation, will Firehouse 51 be able to setup and find out what's the reason behind such gruesome attacks? It certainly seems like an intriguing episode, packed with a shocking accident and twists.

Mills and Severide have some friction going on after he joins the rescue squad. Hopefully, they can resolve their differences. Episode 17 of season three will air on Tuesday, March 10 p.m. ET on NBC.
