Addison is feeling lonely because he has just moved into a new neighborhood, and then he meets Emelina. At first, they have nothing in common and didn't see eye to eye on anything. Addison likes to read and write stories inside, and Emelina likes to be outdoors, jogging, skating, and just about anything that keeps her active. She likes healthy food and Addison has a sweet tooth. A few weeks after they meet, they are surprised to find out that they both signed up for Jr. Detective School. They end up teaming up to solve their first case - a classmate's shoes have disappeared. With very little to go on, Emelina and Addison try to find the shoes. A friendship develops between the two of them when they solve the first of many cases.
