Molly go get 'em (1917)

Young and wealthy Molly Allison can't be "presented" into society until her older sister Julia is married, but that doesn't stop Molly from pursuing her usual wild ways. She finds herself in turn pursued by Count Renaud, unaware that he is a criminal interested in swindling her out of her money. To discourage the Renaud's attentions--and because she already has a boyfriend, Billy Wilcox--she tells Renaud that she is actually an Indian squaw who is just living in the Allison household. That doesn't stop the Count, however, and he turns his attentions to Molly's sister Julia.
