Lilly and her friends are arguing at lunch time about eating good food and bad food because Kendall is eating a chocolate bar. Theresa is mad because Kendall says she is fat and Lilly has to try and keep the peace. When they all go cross-country running, Kendall collapses and the kids don't know what to do, except Lilly.
This latest Lilly adventure shows how children struggle to understand health issues and encourage each other to eat well.
