Chicago Fire just lost one of their own, and two of the firefighters find themselves in the middle of extreme rescues in the very next episode.

"A Real Shot in the Arm" introduces a new firefighter to the firehouse, but Casey (Jesse Spencer) is going to have a problem getting Boden (Eamonn Walker) to sign off on him. And considering what we see in the photos and promo for Episode 2, who can blame him?
