context: The film is set in the reign of King Louis XIII. When ChÃ¢tellerault fails to win the heart of the icy Roxalanne de Lavedan, he wagers his entire estate against that of Bardelys that Bardelys can't either. On the way to the Lavedan estate, Bardelys stumbles upon a wounded and dying man, Lesperon, who asks Bardelys to say farewell to his beloved but dies before telling him her name. Bardelys takes his papers and assumes his identity, only to find that Lesperon is a traitor to the king.
  Bardelys, as Lesperon, encounters the king's soldiers who are hunting Lesperon, fights them, and escapes, badly wounded, to the castle of Lavedan. Roxalanne hides him from the king's soldiers and tends to his wounds. She nurses him to health and pledges her love, but when the guilt-ridden Bardelys refuses to marry her, and in the belief that he is betrothed to another lady, she angrily turns him over to the king's men. Bardelys, still believed to be Lesperon, is brought to trial for treasonâwhere ChÃ¢tellerault is the judge. ChÃ¢tellerault refuses to admit his identity and condemns him to death. Roxalanne finds Bardelys in prison, confesses her love, and agrees to marry ChÃ¢tellerault in a desperate effort to save Bardelys' life. Bardelys escapes from the gallows just as the King arrives to confirm his identity. ChÃ¢tellerault commits suicide rather than be executed by Louis' men. Roxalanne learns of the wager and, mortally insulted, refuses to believe Bardelys when he protests his love. He offers to save the life of her father, who is indicted for treason, if she agrees to marry him. She agrees. He fulfills his part of the bargain but tells her he will not require her promise of her. She confesses her love and begs him not to leave.[2]
