Whedon served as an executive producer, along with Tim Minear. The series is set in the year 2517, after the arrival of humans in a new star system, and follows the adventures of the renegade crew of Serenity, a "Firefly-class" spaceship. The ensemble cast portrays the nine characters living aboard Serenity. Whedon pitched the show as "nine people looking into the blackness of space and seeing nine different things."
