There isn't much drama in Olive Town. The highlight of Cissy Sissney's days are the letters from her old schoolteacher, Miss Loucien, describing her adventures on board an old showboat with the Bright Lights Theatre Company. But then diphtheria breaks out in Olive Town, a silo crushes Cissy's home and Miss May March agrees to take Cissy and classmates Kookie and Tibbie to stay with Miss Loucien until Olive Town is safe again. Cissy and her friends have a host of adventures beating hustlers at their own game, catching criminals, and embarking on a daring rescue mission.
