The massive hydroelectric power development at nearby Niagara Falls and the grand Pan-American Exposition promise to bring the Great Lakes "city of light" even more repute.Against this rich historical backdrop lives Louisa Barrett, the attractive, articulate headmistress of the Macaulay School for Girls. Protected by its powerful all-male board, "Miss Barrett" is treated as an equal by the men who control the life of the city. Lulled by her unique relationship with these titans of business, Louisa feels secure in her position, until a mysterious death at the power plant triggers a sequence of events that forces her to return to a past she has struggled to conceal, and to question everything and everyone she holds dear.
