Olivia "Liv" Moore is a rosy-cheeked, disciplined, over-achieving medical resident who had her life path completely mapped out... until the night she attended a party that unexpectedly turned into a zombie feeding frenzy. As one of the newly undead, Liv has devised a way to resist her baser urges to devour fresh human brains--she's taken a job in the Seattle coroner's office.
In this appropriately dead-end job, she can secretly snack on the brains of the many Jane and John Doe corpses that make a final stop in the morgue. Liv remains resigned to an eternity without hope or purpose, until she realizes that with every brain she consumes, she retains a portion of that person's memories, and she begins to experience visions from the point of view of the murder victims. It's not the same as being alive again, but at least she can find purpose in her undead existence by helping to solve the murders of those who are indeed fully dead.
In the aftermath of the Max Rager massacre, Liv and her friends talk to Vivian to see what she has in mind for a zombie homeland. Meanwhile, Ravi's old boss shows up, Peyton asks Blaine to come over and play cards, and Major finds it hard to get work after being suspect of killing people.
While Liv tries to track down who stole the cure, she and Clive investigate the murder of an aggressively cheerful preschool teacher who was a womanizer on the side. Meanwhile, Major discovers the downside of being human after he has to pretend to be a zombie to stay employed at Fillmore Graves.
An online prankster is killed, and Liv eats his brain and becomes just as obnoxious. Meanwhile, Blaine schemes to reclaim his business from his father Angus, and Liv and Ravi prepare to infiltrate a zombie truther meeting.
Liv and Clive investigate the murder of a D^D dungeon master who lived a secret life. Meanwhile, a woman who understands Major's issues reaches out to him, and Ravi convinces the zombie truthers that he's working on a vaccine.
Peyton convinces Liv to eat some of Weckler's blue brain to learn how he died. Meanwhile, Boss pays Blaine a visit, and the truthers have Ravi keep Don E sedated until they're ready to show the world that he's a zombie.
After Liv and Blaine rescue Don E, Liv eats one of the truthers' brains to try and find out where oldest brother Harley is. Meanwhile, Peyton digs further into the Weckler case, and Ravi explains the facts of death to Rachel.
Ravi's ex-boss and lover Katty turns up dead, and Liv consumes her brain to learn how she died. She soon finds herself dealing with visions of Katty and Ravi being intimate, as well as Katty's impulse to pick up strange men at hotel bars. Meanwhile, Major is outed as a human, and Baracus makes Peyton a job offer.
