Chicago Med Season 12 Episode 2 photos preview “Third Rails,” airing tonight, Wednesday, October 14, at 8/7c on NBC. The new episode brings injured subway surfers into Gaffney Chicago Medical Center’s emergency department, while Hannah and Abrams take an unexpected approach to treating another patient.
Jessy Schram returns as Dr. Hannah Asher, alongside Brennan Brown as Dr. Sam Abrams and Oliver Platt as Dr. Daniel Charles. The episode’s promotional photos also feature Darren Barnet as Dr. John Frost, Steven Weber as Dr. Dean Archer and Luke Mitchell as Dr. Mitch Ripley.
What Is Chicago Med’s “Third Rails” About?
The consequences of subway surfing bring serious injuries to the E.D. Elsewhere, Hannah and Abrams use a surprising creature to help stabilize a patient. NBC’s preview keeps the identity of that creature under wraps, setting up an unusual medical challenge for the two doctors.
Charles has a mystery of his own to investigate. Together, those storylines give the season’s second episode three distinct medical threads, from emergency treatment to an unexplained case that calls for closer attention.
“Third Rails” follows the Season 12 premiere, “Shots Fired.” Before tonight’s episode, revisit our Chicago Med Season 12 Episode 1 photos for a look back at the season opener.
