What happened in Law & Order Season 23? 

Season 23 of Law & Order excelled at balancing hard-hitting cases with character-driven stories, the makings of a must-watch season.

It was a chapter of change for the 27th Precinct: After Frank Cosgrove (Jeffrey Donovan) left the squad at the end of Season 22, Shaw teamed up with his new partner, Riley, to hit the ground running on the latest homicide case. Meanwhile, Pierce and Maroun continued to be rockstars in the courtroom while the investigators finessed hard-to-crack cases around the city. 

Later in the season, McCoy contemplated his long-running tenure amid increasing political tension and ultimately opted to retire from the D.A.'s office. As a cornerstone of the series for nearly three decades, Waterston's farewell was emotional.

After his departure, viewers met his dedicated replacement, Baxter. On his first day, Baxter instantly set out to form steel-tight bonds with the squad while also bringing a fresh perspective to the D.A.'s office. 

"It's a very singular experience to step into something that's such an institution and do it in a capacity where my character's very central now to the story," Goldwyn told People in May 2024. "Stepping into Sam's shoes — I felt honored to be doing that, so it was cool. I felt very excited and privileged.”
