 The captain of the crew of Serenity is Malcolm "Mal" Reynolds (Nathan Fillion) and the episode "Serenity" establishes that the captain and his first mate Zoe Washburne (Gina Torres) are veteran "Browncoats" of the Unification War, a failed attempt by the outlying worlds to resist the Alliance's assertion of control. A later episode, titled "Out of Gas", reveals that Mal bought the spaceship Serenity to continue living beyond Alliance control. Much of the crew's work consists of cargo runs or smuggling. One of the main story arcs is that of River Tam (Summer Glau) and her brother Simon (Sean Maher). River is a child prodigy, whose brain was subjected to experiments at the hands of Alliance scientists at a secret government institution. As a result, she displays schizophrenia and often hears voices. It is later revealed that she is a "reader", one who possesses telepathic abilities. Simon gave up a career as a highly successful trauma surgeon to rescue her from the Alliance, and as a result of this rescue they are both wanted fugitives. In the original pilot "Serenity", Simon joins the crew as a paying passenger with River smuggled on board as cargo. As Whedon states in an episodic DVD commentary, every show he does is about creating family. By the last episode, "Objects in Space", the fractured character of River has finally become whole, partly because the others decided to accept her into their "family" on the ship.
