Rocking Moon (1926)

Sasha Larianoff lives on Rocking Moon Island where she runs a blue fox farm with the help of Gary Tynan. Nash, a trader, has a mortgage on the farm, and Sasha is hoping to pay it off with the season's receipts. But then Sasha's fox pelts disappear, as does Gary. Nash, who is in love with Sasha himself, suggests that Gary is not the fine, upstanding man he appeared to be. This, of course, is untrue -- Gary has been trapped and tied up.
