Who plays Trudy on Chicago P.D.? Actor’s career and notable projects explored

Trudy Platt has been associated with Chicago P.D. since the very first season. The police procedural drama follows the daily lives and missions of officers of the 21st District in Chicago, and Trudy serves as a desk sergeant in the department.

While the sergeant wanted to be a detective, she suffered an injury which led her to take up a less physically challenging job. However, that does not deter her focus, and Trudy plays an important role in the intelligence unit.

Actress Amy Morton plays Sergeant Trudy on Chicago P.D. While the NBC series remains her most memorable work, she has appeared in several other shows and films as well.

Amy Morton’s character and journey on Chicago P.D.

Trudy Platt is introduced as the Desk Sergeant at the 21st District in the first season of Chicago P.D. Before joining the team, she was a patrol officer who passed the detective exam twice but had to step back from fieldwork after being shot in the hip.

Trudy has a tough personality but cares about the people she works with. Though she often gives officers a hard time, she worries about them when they are in danger. For example, she is cold to Nadia, an intern, at first, but when Nadia gives her a birthday card, Trudy softens and helps Nadia work toward becoming a police officer.

When Nadia tragically dies, Trudy makes sure a memorial plaque is placed outside the district. Trudy’s relationship with Mouch McHolland is also a highlight of the show and the franchise. In the 2025 One Chicago crossover, both Trudy and Mouch face serious troubles.

While trying to arrest a man linked to a gas explosion, Trudy is ambushed and shot several times in the back. She falls to the ground and is found by her husband in a pool of blood. She is taken to the hospital, but her fate hangs in balance as she fights for her life.

Initially, it looks like Trudy would not be able to make it, but Chicago Med doctors Mitch Ripley and Caitlin Lenox are able to bring her back to life after much struggle. Trudy now continues to be a part of the show and serves as an inspiration to her juniors.

Chicago P.D. is currently in its twelfth season and airs new episodes on NBC on Wednesdays.
