Twilight at Conner Prairie follows the development of the museum, the conflicts of interest created by the terms of founder Eli Lilly's gifts, and the breakdown of the relationship between the museum and its trustee, Earlham College. Author Berkley Duck, who served on Conner Prairie's independent board of directors when the board and CEO were dismissed, provides an inside look at what went wrong at Conner Prairie and how it was put to right.
