Scottsdale, Arizona, may not be the liveliest place on earth, but it's never been as dead as this. Hundreds of fans have gathered together for the first annual Old Town Zombie Walk, and Mel, Angie, and the Fairy Tale Cupcake crew are donning their best undead attire to sell some horror-themed desserts to the hungry hordes. But the fun turns to fright when Mel finds a real dead body in a prop casket outside of the bakery's truck -- and the corpse looks alarmingly like a zombie of their own. Knowing that Joe, Angie's brother and Mel's former flame, has been working on a dangerous mob case, Mel worries that the murder is a hit gone wrong and that someone near and dear was the real target. To keep any of her friends from winding up six feet under, Mel will do whatever it takes to find a killer -- no matter how scary things get.
