When a fire claims one of their own, there’s plenty of guilt and blame to go around. Lt. Matthew Casey (Jesse Spencer), in charge of the Truck, tries to carry on, but clashes with the brash Lt. Kelly Severide (Taylor Kinney) of the Rescue Squad -- and each blames the other for their fallen team member. Adding to the turmoil, Casey, unbeknownst to his colleagues, is in the midst of a separation from Hallie (Teri Reeves, "Three Rivers"). The firehouse also includes: Battalion Chief Wallace Boden (Eamonn Walker), a fireman’s fireman who is confronted by important personal decisions; paramedics Gabriela Dawson (Monica Raymund) and Leslie Shay (Lauren German), who share a close bond and team together to face some of the most harrowing situations imaginable; Peter Mills (Charlie Barnett), an academy graduate who is the latest generation in a family of firefighters; and Christopher Herrmann (David Eigenberg), a seasoned veteran who loses his home to foreclosure and now must uproot his family to move in with his in-laws.

As his clinical begins, Devon treats his first patient with a revolutionary medical fluid that doesn’t go as planned. Meanwhile, an overdosed John Doe is rushed to Chastain, leading Conrad straight into a much bigger scandal than he expected. Then, a shocking secret regarding Cade’s past is discovered.

When Conrad confronts a pharmacy owner about fraudulent prescriptions being filled under his name, the situation takes a dangerous turn. Then, the ER is sent into chaos when a street racing accident results in multiple severe injuries. Meanwhile, Raptor faces a devastating reality when his mother’s condition worsens.

Conrad and Cade work with a Medicare patient who sheds some light on the inner workings of the prescription fraud situation. Meanwhile, Leela works herself to the brink of exhaustion to avoid having a conversation with Devon and eventually makes mistakes on her cases. Then, the Raptor and Padma try to compromise on how to move forward and Kit and Bell make a big decision about their future.

While the group searches for something to advance their quest, one of them recalls their struggles in the early days of the apocalypse. A game of truth or dare brings emotions to the surface.
