Prosper is a fisherman trying to get by in the face of everyday problems: there's the spectre of the baby his wife desires, the ghost of his dead mistress, his wife's secret admirer, and the overwhelming lure of the village bar. When a slippery eel salesman arrives in town peddling progress to the rural community, Prosper's list of problems only increases. Faced with an invasive new species in his lake, his fortunes decline along with the fish population, and Prosper gets a lesson in gift horses and generosity.
