[Teuthida]

The series is set in 2517 AD and follows the adventures of the renegade crew of Serenity, a Firefly-class spaceship. The ensemble cast portrays the nine characters who live on Serenity. Whedon pitched the show as "nine people looking into the blackness of space and seeing nine different things".[4] The show explores the vicissitudes of people who fought on the losing side of a civil war, as well as the pioneer culture that exists on the fringes of their star system. In addition, it is a future where the only two surviving superpowers, the United States and China, fused to form the central federal government, called the Alliance, resulting in a fusion of the two cultures, as well. According to Whedon, nothing has changed in the future: there are more people with more advanced technology, but they still have the same problems politically, morally and ethically.

Kind of find it odd that someone could enjoy the movie without watching the show; it's sort of like the last episode. Guess you'll love the series then.
