CBS has finally given fans a glimpse of Vanessa Lachey‘s Jane Tennant in a new teaser for the upcoming spinoff series NCIS: Hawai’i.

Tennant is the first female Special Agent in Charge of NCIS Pearl Harbor, which also makes her the first female character to lead an NCIS series. And Lachey shows off that confident leader mentality in the trailer, guiding her team in the fight against the various criminal activity in the Aloha State.

“When anyone on my team gets in trouble, I’m the first call,” Tennant says as we’re treated to clips of fistfights, shoot-outs, explosions, and car chases. It’s also clear the character has a sarcastic sense of humor, as she tells a colleague, “You haven’t had the pleasure of my ‘we work as a team speech,’ but you can guess the bullet points.”

Tennant is officially described as “a keen investigator who can navigate a crime scene and inter-bureau politics with equal aplomb.” She is also the mother of a 15-year-old boy and a 9-year-old girl and is often torn between caring for a family and investigating high-stakes crimes involving military personnel and national security.

“They don’t just show her sitting behind a desk,” Lachey recently told us in between filming (check out the NCIS: Hawai’i cover story in TV Guide Magazine, on newsstands now). “She’s out there and, yes, she asks her team to help out. She’s [all about] love of country and love of family, so I love that I get to bring that to the screen for everyone to watch.”

'I understand because I firsthand lived with sacrifices that my father made for us and for the country. It definitely runs in my blood,' she says.
