A little boy named Dickie Cessna (Scott Schwartz), who lives at a country club where his father works decides to make some extra money by selling composted horse manure as fertilizer, and has his three sisters, Nene, June and Bette (two of which are older) join him in the enterprise. As their sales increase, they draw increased scrutiny from the state tax board, as well as the large scale competitor who seeks to put them out of business at any cost.
