Question: Question: Who exposes Montrose's plan to frame the Duke of Argyll? If there is no answer, please output "Insufficient information to provide an answer.". Movie title: Rob Roy Context: In Scotland, 1713, Robert Roy MacGregor (Liam Neeson) is the Chief of Clan MacGregor. Providing the Lowland gentry with protection against cattle rustling, he barely manages to feed his people. Hoping to alleviate their poverty, MacGregor borrows 1,000 from James Graham, Marquess of Montrose (John Hurt) in order to trade cattle. Impoverished London aristocrat Archibald Cunningham (Tim Roth) has been sent to stay with Montrose, who it is implied is related to him, as his debaucheries have become a problem back in England.

Unaware of the assault on his wife, but the damage to his property being all too evident, MacGregor refuses to permit his outraged clan to wage war on Montrose. Instead, he decrees, "The tenderest part of the Marquess is his purse. We'll hurt him there. Thieve his cattle, steal his rents." It transpires that Betty (Vicki Masson), a maidservant at Montrose's estate, has become pregnant with Cunningham's child. When Killearn tells Montrose, Betty is dismissed from service and...
