Serenity

The feature-length adaptation of Joss Whedon's TV show Firefly, set five hundred years in the future aboard Serenity, a transport ship captained by Capt. Malcolm "Mal" Reynolds. The crew of Serenity takes on any job that will pay, even if it's not exactly legal. Malcolm Reynolds (Nathan Fillion), the captain, was on the losing side of a galactic war, and now all he has is his ship, named Serenity, and his loyal crew: his second in command and most trusted ally, Zoe (Gina Torres), her husband, the pilot, Wash (Alan Tudyk), the mechanic, Kaylee (Jewel Staite), and the muscle, Jayne (Adam Baldwin). When Malcolm takes on two new passengers, a young doctor, Simon Tam (Sean Maher) and his unstable, telepathic sister River (Summer Glau) he gets much more than he bargained for. The two are fugitives from The Alliance, the conglomerate that controls the galaxy. River learned something no one was ever supposed to know... and The Alliance will do anything to make sure no one will.
