Set against the backdrop of Long Beach, California, On Call chronicles the partnership between seasoned officer Traci Harmon (Troian Bellisario) and impulsive rookie Alex Diaz (Brandon Larracuente). Still mourning a trainee’s tragic death, Traci enforces rigid protocols to protect Alex. Hower, his rebellious nature challenges her authority and forces both to confront their vulnerabilities. Shot using a mixture of hand-held cameras, bodycam, and dash-cam footage, the series offers an intimate look at their evolving partnership while addressing the emotional toll and ethical dilemmas inherent in modern policing.

The partnership between Traci and Alex is the heart of the series. “The entirety of the show really is about this relationship and as a small microcosm of something much larger,” explained Bellisario to SciFi Vision during a recent interview with the press. “I think what's really incredible about the opportunity that we give our audience is you really get to come in to the patrol car with us. You get to spend all of this time with us going from call to call to call, really not getting any breaks. You never see us at home. It's not about our personal lives; it’s about our lives out in the community doing this job.”

The actress added that the relationship grew organically. “Getting to go to work each day with in incredible scene partner, I think the relationship really had an organic build to it. The more Harmon and Diaz got to know each other and trust each other, so too did myself and Brandon.”

According to Larracuente, it comes down to the writing. “I feel like Tim [Walsh] and Elliot [Wolf] and the rest of the writers did an incredible job at creating these characters that come from all different walks of life,” the actor told the site. “People from Bishop to Lastman to Diaz to Harmon, they all have a different way of the world and a different way of policing, and to see all of those people in the same environment having to interact and having to work towards a common goal, I feel like that's what was most interesting to me, especially now that I'm able to see the show and witness it as a spectator.”
