For three best friends, a small town, endless days of summer and an old radio form the recipe for an unforgettable adventure. It's summer in Delley, a quiet town in the American Midwest. Perhaps too quiet for Jeremy, Stella, and Sam, three inquisitive kids with a desire to solve mysteries and seek adventure in a place that, to be honest, doesn't offer a lot of either. However, when Jeremy gets an old radio that connects him and his friends to a girl who needs their help, the adventure they find themselves in may be a bit more dangerous than they hoped for.
