Mira and Bella are friends who treat each other as sisters. One day, Bella got into an unintended repercussion-shortly after receiving the wrong vaccine to prevent herself from acquiring the virus, she found a red bead that would make her the queen and ruler of all zombies. To stop humanity's doom, Mira has to destroy the bead that has the power to control the undead, which has already become a part of Bella's body and spirit. Will Mira be able to eradicate Bella and save the human race? Will Bella control the bead, or will the bead entirely dominate her?
