Alden Parker is on a quest for revenge in the season 23 premiere of NCIS. 

On Monday, CBS revealed a first look at the first episode of the long-running procedural’s new season, which will feature Last Man Standing and Grosse Pointe Garden Society alum Nancy Travis in a key role. 

Parker hunts for his father’s killer in the ‘NCIS’ Season 23 premiere  

NCIS returns on Tuesday, October 14 with the first half of a two-part season premiere. In “Prodigal Son (Part 1),” Parker (Gary Cole) is still reeling from his father Roman’s (Francis X. McCarthy) murder in the season 22 finale. The grieving NCIS chief goes to extreme lengths to hunt down the woman he holds responsible for the crime. But his fixation on mob boss Carla Marino (Rebecca De Mornay) jeopardizes not only his own future but the team’s as well.  

In season 23’s first episode, viewers will also meet Parker’s sister, Navy Vice Admiral Harriet Parker. Her character’s arrival will shed more light on Parker’s complicated past. 

“The Alden Parker that we know and see now is not what Alden Parker was as a child,” NCIS showrunner Steven D. Binder told TVLine. “We’ve gotten into his history a bit — he was a troubled kid, he was in a juvie home, he stole things — and that’s the dynamic that his sister grew up with. He was the ‘bad’ kid and she was the good kid.”

That good kid vs. bad kid dynamic will resurface in the wake of their dad’s death, Binder added. 

“They’re going to relive that between the two of them,” he shared. “She’s this super squared-away Navy admiral, and then you’ve got Alden Parker, who’s got this ‘bad kid ‘seed. Those two are going to come to a head ​​and what’s funny about that is it’s one thing to have it happen over Thanksgiving dinner, it’s a whole other thing to happen in the middle of a global crisis! The bickering is, I might say, very NCIS.”

CBS also shares details about ‘NCIS: Origins’ and ‘NCIS: Sydney’ return

CBS has also shared synopses for the season premieres of both NCIS: Origins and NCIS: Sydney.
