At an amateur circus given by banker
Fontenoy for his guests, Elena, his mistress and the wife of the
Marquis Torre De Bianca, meets Robledo, her husband's boyhood
friend, who has just arrived in Paris from the Argentine.
Fontenoy is insanely jealous of Robledo
and upbraids Elena for flirting with him. Yet, she leaves
Fontenoy upon discovering his financial ruin, and he commits
suicide.
Bianca, humiliated by the scandal,
retires to the Argentine with Robledo, who is supervising the
building of a dam, and takes Elena with him.
Although Robledo resents Elena's
presence, he fights Duros, a local outlaw who is enamored of her and
who tries to kidnap her, and a quarrel over her erupts into murder.
Duros dynamites the dam, and the
villagers flee from the resulting flood. Robledo swears to
kill Elena, but passion overcomes his wrath. Realizing her
defeat, Elena leaves him and returns to Paris, where she sinks to
drunkenness and degradation.
