In a last-ditch attempt to save their failing marriage after the stillbirth of their first child, Kate, a journalist, and Martin, an architect, escape London for a retreat to the beautiful, yet remote and unpopulated Blackholme Island, which is off the west coast of Scotland. Fairweather Cottage is a place where they once shared a romantic holiday and the island holds fond memories of happier times. Kate and Martin arrive by boat, it's autumn and the rocky barren moors are blown by freezing winds and the before they've even settled in, the generator and CB radio communication start to fail. Their relationship is already fragile and anxieties are pushed higher when they lose all contact with the mainland and after a heavy storm, an injured man is washed up on the shore. Dressed in military fatigues and carrying a gun, the mysterious stranger regains consciousness and identifies himself as a British soldier called Private Jack Corman and he soon reveals that he carries a deadly message - an airborne virus is sweeping Europe and all their lives are under threat unless they take drastic action. He insists that the only way to avoid the fatal disease is to seal themselves in the cottage.

How to Watch Retreat Legally and Safely

If you want to stream Retreat 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 Retreat 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.
