Joss Whedon, Emmy Award-nominated creator of Buffy the Vampire Slayer and Angel and an Academy Award nominee for Toy Story, brings his unique and multi-talented skills to FIREFLY, a sci-fi/western adventure series.
Set 500 years in the future, in the wake of a universal civil war, FIREFLY centers on the crew of Serenity, a small transport spaceship that doesn't have a planet to call home. Captain Malcolm "Mal" Reynolds (Nathan Fillion), a defeated soldier who opposed the unification of the planets by the totalitarian governed Alliance, will undertake any job — legal or not — to stay afloat and keep his crew fed.
With prostitution now legal among the planets, the beautiful and sophisticated Inara (Morena Baccarin) has her own shuttle docked on the ship and shares friendly, yet non-sexual relationships with the crew while serving as a paid companion to the Serenity's guests. The wealthy and secretive Simon (Sean Maher) joined the crew as the ship's doctor in the hopes of protecting his emotionally fragile, yet intellectually gifted younger sister, River (Summer Glau).
Rounding out the ship's permanent denizens is Book, "The Shepherd" (Ron Glass), a preacher who is on board to spread the Word of God to the far reaches of the galaxy.
Thrust together by necessity, these disparate men and women are seeking adventure and the good life, but face constant challenges on the new frontier, such as avoiding capture by the Alliance, and evading death at the hands — and mouths — of the Reavers, human, flesh-eating mongrels who live on the fringes of the universe.
