Serenity

US sci-fi adventure written and directed by Joss Whedon. 500 years in the future, after a galactic civil war has united all the space colonies under the repressive Alliance, former rebel soldier Mal Reynolds (Nathan Fillion) captains the Firefly class cargo ship Serenity, taking on odd jobs and scoring heists where he can to keep his ship and his crew in the air. When he picks up Simon Tam (Sean Maher) and his disturbed sister River (Summer Glau), Mal ends up with more trouble than he could have bargained for.

On the run from the Alliance, River has been the subject of horrific government experiments to develop her latent psychic powers. Determined to get her back, the Alliance dispatches ruthless assassin The Operative (Chiwetel Ejiofor), leaving Mal and his crew battling for survival as they race across the galaxy. However, when they then discover an even darker secret the Alliance would like to keep hidden, Mal and his companions finally have their chance to hit back.
