Anton Chekhov's The Duel

This 2010 drama adapts Chekhov's story of Laevsky, a drifting man trying to extract himself from his affair with Nadya after pushing her to leave her husband for him. Fiona Glascott plays Nadya, and the archive has 1 clip of her nude on site. The scene is the only reason this title shows up in a search for her name.
