Firefly was a 2002 American space Western drama television series, created by Joss Whedon, who previously created Buffy The Vampire Slayer.
Set in the year 2517, humans have left Earth and settled in other planets in another star system. The series follow the crew of the spaceship Serenity, a Firefly-class ship, and their adventures throughout the star system.
The series was cancelled after 14 episodes. Due to Firefly's popularity with fans and strong DVD sales, a 2005 movie, Serenity, was released as a proper finale for the series.
