Who knows that an abnormal decision completely subverts her established destiny. Unable to withstand the persuasion of her peers, she attended a rave party held on a ship. However, a mysterious drug at the party turned everyone into a bloodthirsty and violent zombie. The next morning, Olivia sat up from the body bag. She was obviously dead, but now she was resurrected as a zombie. The huge change in appearance and temperament and the terrible experience made her family at a loss, and the desire for the brain in her body also made her anxious. For this reason, Olivia found a job in the Seattle Coroner's Office. From then on, she had a stable source of food. At the same time, she found that she also had the memory of the dead...
