First taking a look at the mystery crime series, Big Sky, three private detectives join forces to track down two abducted women in Montana.

Jesse James Keitel and Dedee Pfeiffer, who play Jerrie Kennedy and Denise Brisbane, teased the puzzling mysteries and groundbreaking representation in the new season.

"Season two picks up right where season one left off. We got Ronald, our big bad, and then he got away, and in the crossfire, our heroes are leaving with some serious injuries, so season two is picking up in the aftermath of that," Keitel said.

Keitel is also making big strides in the LGBTQIA+ community by playing one of TV's first non-binary characters.

"There's a huge responsibility with that, and I feel that, and I think I approach my work that way as well, knowing there may be some grandparents out there who can embrace their queer grandchildren and children after falling in love with a character like Jerrie," Keitel said.

Dedee Pfeiffer also touched on Keitel's important role in Big Sky.

"I'm just really excited to be on ABC's show, who did this [and] brought her on. I love to say in almost all my interviews how proud I am to be on this show with this woman," Pfeiffer said.

Watch Keitel break down barriers in Big Sky, airing Thursday nights on ABC.
