Young "hacktivist" twin sisters Anna and Benni are inseparable in their quest to expose environmental wrongdoing by any means necessary. But when their hack into a government server leads to a police raid, Anna is captured and Benni disappears into the underground. When it becomes apparent Benni is lending her skills to a radical new terrorist group that does not shy away from violent action against state and corporations, the sisters suddenly find themselves on opposite sides of the question: What line are you willing to cross for something you believe in? 

How to Watch A Thin Line Legally and Safely

If you want to stream A Thin Line 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 A Thin Line 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.
