After producing Buffy and Angel, Joss Whedon turned his hand to science fiction. The result was Firefly, a science fiction show with a cowboy mentality.

After being on the wrong side of a stellar civil war, captain Malcolm Reynolds becomes a low-level outlaw, travelling the known worlds with a diverse crew and making money any way he can.

The story begins as he picks up passengers - straightlaced doctor Simon Tam and his sister, River. The problem is that Simon and River are fugitives, and picking them up means that Malcolm and his crew are now at the top of the authorities' wanted list.

It's an interesting premise, bought to life by a fine ensemble cast. And the world they live in is interesting too - the United States and China have joined forces to create the Alliance, a body which rules the inhabited planets featured in the show. The result is a mismatch of cultures and languages.

Only 14 episodes of Firefly were produced, and they're all here. The show was cancelled prematurely, but the fan outcry was such that a film, Serenity, was later produced to finish off the story.
