Life is sweet and business is booming at the Fairy Tale Cupcakes bakery--and the fact that Mel and Joe are getting married is the icing on the cake. Their reception will be held at the swanky resort where Oz works as the pastry chef. The wedding planning is all fun-fetti and games until Mel and Joe meet the head chef at the resort who has been making Oz's life miserable. When the eccentric chef insults Mel's bakery, Oz gets into a blowout argument with the culinary prima donna.
Things turn extra sour when the chef is murdered, and Oz is the police's main suspect. As the countdown to the wedding day begins, Mel, Joe, and the rest of the Fairy Tale Cupcake crew must sift through clues to catch the real killer and clear Oz's name before their wedding plans are totally battered and baked.
