Each video begins with the girls singing the theme song. Following the theme song, the girls receive a phone call, informing them of some urgent mystery that needs to be solved. Their motto is "Will solve any crime by dinnertime." Each video features the girls singing multiple songs about the mystery they are working on. They never fail to solve the mystery with their sidekick, Clue (a Basset Hound), and, indeed, the solution is usually something either very obvious or very trivial, to give the video a humorous ending.
