Beau, John, and Digby Geste are three inseparable, adventurous brothers who haven been adopted into the wealthy household of Lady Brandon. When money in the uppercrust household grows tight, Lady Brandon is forced to sell her most treasured jewel the mighty "Blue Water" sapphire. The household gets it out for one final look, the lights go out and it vanishes stolen by one of the brothers, no doubt. That night, Beau, Digby, and John each "confess" and slip out, John leaving behind Isabel, whom he loves. They all join the Foreign Legion, and Beau and Digby are split from John and put under the command of the ruthless and sadistic Sergeant Markoff. Things begin to get hairy as the rest of the Legionaires plot a mutiny against Markoff, in the midst of an attack by Arab hordes.

How to Watch Beau Geste Legally and Safely

If you want to stream Beau Geste 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 Beau Geste 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.
