Protecting Romero High from all things supernaturally spooky as Dia Muerto is a tough gig for sixteen-year-old Dia Summers, but it's nothing compared to protecting the ones she loves from real, live-well, formerly alive-zombies. Unlike the zombies that shambled around on set, the real deal don't follow a script. At the majorly important birthday party of her boss' daughter, Dia experiences a series of potentially career-ruining social disasters. Before the night is over, she soon discovers that the possible cancellation of her show isn't her biggest worry. Armed with what they can find around Bixby Studios, Dia and her friends band together to find out why everyone they know has begun popping up as gray-skinned, black-eyed, limb-nomming zombies. With the ailment spreading, time is running out before Dia is swept up in Hollywood's latest trend.
