Nancy, Bess, and George are considering joining the farm's CSA program when a fundraiser showcasing the farm's produce turns into a health nightmare, with several attendees falling ill from E. coli contamination. Sam, the farm owner, insists that his produce is clean and the contamination must have been caused by an external factor. But after an intruder destroys the farm's greenhouse and kills the chickens, the girls suspect foul play. Can Nancy and her friends uncover the culprit and stop the farm from being destroyed?
