Between "iZombies" Season 1 and 2, the show has been pulled in a few different directions. In Season 1, Liv struggled with herself, her new identity as one of the undead and what that meant for those she was close to; in Season 2, she fought a very real and tangible threat in Maxx Rager, the evil corporation whose energy drink formula created zombies. Moving into Season 3, Liv will come up against army contractor Vivian Stoll and her zombie-run company Fillmore-Graves, again facing a drastically different kind of threat. During a set visit, star Rose McIver assured CBR and other reporters that the show will maintain its familiar feel nonetheless.

"[Co-creators] Rob [Thomas] and Diane [Ruggiero-Wright] have done such a great job of including enough of the elements that will feel very familiar. I mean, the device of having a different brain each week and having the morgue and having the police station and these familiar things that keep it feeling like the same show, that reinventing it enough that we don't feel like we're watching the same season again," explained McIver. "We are watching new dynamics that are created each year, so I feel crazy lucky. I mean, we keep saying, 'Well, what would Season 4 be? What's next?' Like, we know what we're dealing with now. I don't even know quite yet what we're building towards with the finale for Season 3, but I know that Season 4 will be something entirely new again, so I'm sniffing around, trying to find out where this is going."

Like McIver said, the show will maintain some of its more familiar aspects, including the show's procedural nature. "We will continue to see procedural. We like solving those crimes," confirmed executive producer Dan Etheridge. "Obviously, Clive and Liv as detective duo is a wonderful and amazing relationship. I don't think I'm speaking out of school to say you will see that in every subsequent episode after [season] 3 [episode] 1. You will see the procedural. I don't think we wanted to be chained to it for the rest of the existence of the series, but I am not suggesting that we will be moving wholesale. Is it possible that this is the beginning of every once in a blue moon? But [season] 3 [episode] 2 through [season] 3 [episode] 9, which we're shooting now, we continue to see it."

Based on the Vertigo comics series by Chris Roberson and Michael Allred, “iZombie” follows the story of Liv Moore, a former medical resident who got turned into a zombie. In order to satiate her appetite for human brains, she takes a job at the Seattle coroner’s office and feasts on the cadaver.
