Chicago P.D.was the first successful spinoff of the One Chicago franchise, and the police procedural has been renewed for season 13. Created by TV maven Dick Wolf and Matt Olmstead, Chicago P.D. follows the officers of the police department’s Intelligence Unit as they use their unique set of skills to crack some of the toughest cases that the city has to offer week after week. Across its decade-plus on the air, the series has expanded to not only tackle case-of-the-week stories, but also weave interesting narratives about the characters’ lives as well.
