Ellie and her women's business group, the Greenstockings, are helping to open a new museum about local history, and while sorting through the collection of artifacts they discover a time capsule from the days of the Gold Rush. Among the contents is a strange botanical manuscript, recognized by local history professor Eureka Sanford as extremely rare and valuable. When the professor is found dead in the museum, Ellie has no choice but to sniff out the murderer... but this one may have roots that are as old as Poppyville.
