iZombie (TV) - How Does Liv Become The Undead?

Bloody Disgusting brings us the following plot synopsis for the series, which stars Rose McIver as Liv:

Now stuck somewhere between half-alive and undead, Liv loses all traces of her former drive and ambition. She breaks off her engagement with charming soulmate Major, fearful of infecting him with her condition. She withdraws from her best friend and partner in overachievement, Peyton. And, perhaps most worrisome to her caring but overbearing mom, Eva, Liv transfers her medical residency to the city morgue in order to reluctantly access the only real form of sustenance left available to her — and the only thing that allows her to maintain her humanity — human brains.

But there are side effects to Liv’s new diet: With each brain Liv consumes, she experiences “visions” — flashes of the corpse’s memories — including, in some cases, clues as to how they were killed. Her boss, the brilliant but eccentric conspiracy theorist Dr. Ravi Chakrabarti, encourages her to embrace this gift and to work with an eager, unproven homicide detective, Clive Babineaux, to help solve these murders. In doing so, Liv finds a measure of peace, and a new sense of purpose in what her “life” has now become.
