At 30, boyish penniless aristocrat Ryno de Marigny has separated from Villini, a passionate Spaniard and his mistress of 10 years. He’s now in love with Hermangarde, a young, wealthy, and titled virgin. Days before the wedding, the bride’s grandmother sits Ryno down and insists on knowing if his affair is over. He relates a story of passion, which we see in flashbacks, swearing he loves only Hermangarde. After the wedding, the couple moves to a castle by the sea. And Villini? Can passion survive disgust and self-loathing?

How to Watch The Last Mistress Legally and Safely

If you want to stream The Last Mistress through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry The Last Mistress films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
