Firefly - episode 1 (pilot) - Serenity (complete episode)

The crew of Serenity takes on several passengers and make their way to another planet to try and sell goods they salvaged from a wrecked ship. Their efforts are impeded, though, when Wash and Mal realize that there is an undercover aAlliance agent on board. Simon struggles to save Kaylee, and in turn River and himself while Mal, Zoe, and Jayne attempt to unload the cargo from the salvage to a trigger-happy mayor of a border moon.
