As Dr. Ethan Choi (Brian Tee) treats a bleeding teenage girl, he discovers she's just given birth, sparking a frantic search for her abandoned baby. When the details of the teen's troubled past emerge, Ethan finds himself at odds with pediatrician Dr. Natalie Manning (Torrey DeVitto) and hospital administrator Sharon Goodwin (S. Epatha Merkerson) as they're forced to make some difficult decisions about the teen's future. Dr. Will Halstead (Nick Gehlfuss) treats a hypochondriac with chest pains while struggling to navigate his overbearing wife. Meanwhile, med student Sarah Reese (Rachel DiPillo) and psychiatrist Dr. Daniel Charles (Oliver Platt) treat a patient suffering from dementia, only to discover she may not have dementia at all.

Everyone in the firehouse is ordered to take a drug test after a call to a daycare center exposes them to a makeshift meth lab, and Severide stalls, not wanting his injury, or the painkillers he takes, to be discovered. Meanwhile, Truck and Squad find themselves pinned down by gunfire while trying to help the victim of a gang shooting, and a deep-fried turkey fire grows from small to explosive when a garage catches fire. Elsewhere, Dawson saves a bleeding man and Casey delivers a baby on the scene of a massive car pileup on the freeway.
