Returning to his native Rio after many years abroad, Aires is captivated by a young widow, Fidela Noronha, whom he sees praying at her husband's graveside. Her charm and the tragic story of her brief marriage increase his fascination, and soon he is indulging in impossible dreams. But the Brazil that Aires remembers from his youth is changing fast. A new era is dawning with events such as the coming of the railway and the abolition of slavery. The future belongs to a younger generation, to men like Tristao, the doctor and political candidate, who is also an admirer of the beautiful Fidelia. The Wager is a story of broken dreams, love and obsession - universal themes that give de Assis's work the timeless quality for which it is renowned.
