After Gioconda defies Silvia to take her husband back, Lucio shoots himself in a fit of desperation. Although Silvia nurses him back to health, Lucio soon returns to the enticing Gioconda. When Silvia's subsequent quarrel with Gioconda becomes a fight, Gioconda attempts to destroy Lucio's statue, but it falls on Silvia and is saved. Silvia, however, is crippled for life. Because of this, Lucio's sanity is affected and he becomes a raving maniac. Later, cast aside by her "man of the world," Gioconda also descends into madness. A lost film.
