The Corsican Brothers

In Corsica, Count and Countess Franchi welcome twin boys. Dr. Enrico Paoli informs the Count that his wife has given birth to Siamese twins. The Count insists on separating them, despite Paoli's warning that the babies' survival would be miraculous.

Before separation can begin, Colonna's forces launch a surprise assault on the Franchi clan. Almost all Franchi are killed, but the newborn twins are carried to safety by Paoli and Lorenzo.

Paoli successfully separates the twins: Mario is taken to Paris to be raised by Monsieur and Madame Dupre, while Lucien remains with Lorenzo in the Corsican hills. Paoli questions the wisdom of the separation but decides it's the only hope.

Two decades pass. Lucien leads a band of outlaws in Corsica, while Mario's life unfolds in Paris. At a Paris theatre, Mario saves Countess Isabelle Gravini from a rude Marquis, but is stabbed; Lucien feels the same pain, despite being far away.

At age twenty-one, Paoli brings the brothers back together. They vow to avenge their parents by killing Colonna, now a tyrant in Corsica. Lucien confirms that his shared sensations with Mario were real.

The twins begin slaying Colonna's relatives, often pretending to be the same person to confuse their foe. Colonna is left guessing how the Franchi brothers could appear in two places at once.

Colonna plans to marry Isabelle Gravini. When Isabelle's father refuses, he is poisoned in his own home. Mario reveals Colonna's intentions to Isabelle, who flees with Mario to the bandit camp, where they fall in love.

Lucien confesses his love to Isabelle and is rebuffed. Paoli cannot answer, leaving Lucien to decide that he must kill Mario to be free to live his own life. He attempts to force a confrontation, but Lorenzo breaks up the knife fight.

Isabelle decides to return to Paris to avoid rift between brothers. En route, she is spotted and taken to Colonna.

Tomasso figures out that the Franchi twins are behind the attacks. They set a trap using Isabelle as bait. Mario, aided by Maria, attempts a rescue but is captured and whipped to reveal hunting grounds. Paoli is forced to attend; a drug makes Mario seem dead but he is later revived.

Lucien, believing Mario is dead, leads his men against Colonna. He is fatally shot in the back by Tomasso, but not before he kills Tomasso himself. Mario then appears and braces for a final showdown.

In a climactic sword fight, Mario defeats Colonna, ending Colonna's tyranny. Lucien dies just after reconciling with his brother, sealing the Franchi bond and the brothers' shared fate.
