A tale centering on Emily, a plucky pre-teen (and violin virtuoso) who is entrusted with her young neighbors' most private and cherished secrets. Every Wednesday, Emily sets up a booth in her backyard which regularly attracts the guilty young souls of the neighborhood. These include Philip - the new kid on the block - whose clumsiness with an expensive chess piece (and his interest in Emily) make him one of her most challenging clients. But comedic complications ensue when the Secret Keeper -normally so trustworthy - suddenly finds it difficult to keep all of her neighbors' secrets to herself.
