Life's great for young doctor Liv, until she's turned into a zombie. Now she's a brain-eating coroner with a nice knack for catching killers.

While brains-eating Liv helps solve the murders of a stripper and other victims, Major struggles with his own changes and Peyton reenters Liv's life.

Liv faces a rising foe in Vivian Stoll, head of Fillmore-Graves Enterprises and a visionary whose long-term plan is to make Seattle a zombie capital.

In the aftershock of Discovery Day, Liv tangles with black marketeers, street gangs and other perils plaguing Seattle, now a zombie segregation zone.

In the final season, zombies in Seattle face a critical food shortage, Major takes the reins at Fillmore-Graves and Liv's fate hangs in the balance.
