Nancy's (Kennedy McMann) far from a pushover, but she's up against a formidable adversary as she and iron-willed local matriarch Celia Hudson (guest star Teryl Rothery) go head to head in the new episode "The Trail of the Missing Witness," directed by actress Kristin Lehman ("Motive"). Elsewhere, Nick (Tunji Kasim) hires a new line cook at The Claw. Scott Wolf, Leah Lewis, Maddison Jaizani, Alex Saxon and Riley Smith also are featured.
