Everyone agrees that Lucy McGuffin bakes the best muffins in Whispering Bay, but she's got another talent, one that she's tried her whole life to hide. Lucy can always tell when a person is lying or telling the truth. Being a human lie detector isn't all that it's cracked up to be. Especially when you really don't want the answer to the universal question: Does this dress make my butt look big?
When Lucy is hired to cater the grand opening of the new community center, she stumbles across the dead body of Abby Delgado, a prominent member of the Sunshine Ghost Society. Lucy's brother, Sebastian, a local priest, is the last person to have seen Abby alive. Convinced he'll be breaking a confidence, Sebastian refuses to cooperate with the police, forcing Lucy to put her skills to the test to save her brother's good name.
Enter the town's new hotshot deputy, Travis Fontaine. Travis doesn't want an amateur like Lucy sniffing around his turf, so he offers her a deal. He'll stay out of her kitchen if she stays away from his crime scene. But Lucy isn't about to let her brother's fate rest in the hands of an arrogant cop. Good thing she has her best friend Will and her new little rescue dog Paco to back her up, because it's up to Lucy to figure out what everyone in the quaint little beachside town is hiding.
