On Christmas Eve, Swiss minister Jean Martens takes in a blind, half-crippled orphan and brings her up among his own four children. But Gertrude grows into a woman and Jean gradually falls in love with her without admitting it to himself. On the contrary, he lulls his conscience by interpreting the Scriptures to his advantage. But neither his wife nor his oldest son are fooled. Following a long-delayed operation, Gertrude recovers her sight but she is not long to find out that sin has corrupted the soul of her benefactor.

The film is a 125-minute, black-and-white biography of French priest and diplomat Charles Maurice de Talleyrand-Périgord (1754–1838), who served for 50 years under five different French regimes: the Absolute Monarchy, the Revolution, the Consulate, the Empire, and the Constitutional Monarchy. Its title comes from one of the main historical nicknames for Talleyrand, that he shares with demon king Asmodeus and English poet Lord Byron.
