Joss Whedon's Firefly - 2002

Captain Malcolm "Mal" Reynolds and his crew aboard Serenity illegally salvage goods from a derelict ship. Because the Alliance marked the goods, and an Alliance ship spotted an obsolete Firefly-class freighter leaving the scene, Mal's fence Badger refuses to handle the goods. Mal has to sell elsewhere. To make extra money, the crew picks up passengers: Shepherd Book, Simon Tam and Lawrence Dobson.

Crime lord Adelai Niska hires the crew to rob a train of unspecified goods. The crew can transfer the goods to Serenity flying above, but Mal and Zoe Washburne are forced to stay behind on the train. They learn that they have stolen medicine desperately needed by the locals. The crew argues whether they should deliver the goods to Niska. Ultimately, they decide to rescue Mal and Zoe first through subterfuge.

The crew discovers a derelict ship that was attacked by Reavers and take aboard the sole survivor. Shortly after, an Alliance cruiser orders Serenity to dock to it. Simon and River hide to avoid capture. The rest of the crew are interrogated. Refusing to believe in the existence of Reavers, the Alliance's Commander Harken decides that the crew will be charged with attacking the ship and murdering its settler passengers.

Inara Serra is hired by Atherton Wing, one of her regular clients, and accompanies him to a formal dance. Badger hires Mal to meet a contact at the same dance and try to set up a smuggling job. When Mal hits Atherton for the way he treats Inara, Mal finds he has unknowingly challenged Atherton to a duel with swords. Atherton is a skilled swordsman and duelist. Inara tries to teach Mal how to use a sword overnight.

The crew delivers cattle to the Rim, but Book is gravely injured when they are stuck in the middle of a shootout. At the same time, Simon and River Tam are kidnapped by locals while sightseeing in town. Mal chooses to leave the Tams behind to seek help for Book. Desperate, they turn to an Alliance ship. At first hostile, the Alliance officer they speak to provides medical aid after seeing Book's ID. Meanwhile, the kidnappers belong to a community in desperate need of an actual doctor, and Simon tentatively hopes he has found a haven for himself and River. However, the religious residents believe River is a witch and attempt to burn her at the stake.

After completing a job for a small settlement, during the ensuing celebration, Mal learns that he inadvertently married a young woman called Saffron, part of the payment. Although Mal insists they are not married, Saffron is determined to fulfill a subservient wife's role. Saffron is not what she appears to be.

The crew lands on a planet to meet a contact. Although Jayne Cobb insists he is wanted there, they are dumbfounded to learn that the locals revere him as a folk hero. Mal attempts to use Jayne's status as a distraction to move smuggled goods across town. However, Magistrate Higgins releases Jayne's former accomplice Stitch Hessian, whom Jayne abandoned years ago during a botched robbery and now seeks revenge.

An explosion in the engine room leaves Serenity with the engine and the life support system and its backup all out of commission. With only a few hours of oxygen left, Mal has the crew leave in the two shuttles while he remains aboard and hopes to contact a passing ship. In a series of flashbacks, Mal convinces Zoe, Jayne, Inara, Hoban Washburne, and Kaylee Frye to join his crew.

While waiting on the Core planet Ariel, Simon hires the crew to help him smuggle River into a local hospital for a thorough diagnostic. In return, he will tell them how to loot the hospital for valuable medicine. Once inside, Jayne attempts to turn in Simon and River for the reward. However, the Alliance officer arrests Jayne as well to keep the bounty for himself.

Angry that Zoe and Mal have an unshakeable bond as war veterans, her husband Wash demands to take her place on a seemingly routine mission. Mal begrudgingly allows Wash to go along. They are captured by Niska, out to restore his reputation after they failed to complete the robbery he commissioned in "The Train Job".

When Saffron crosses paths with Mal again, she asks him to help her rob a precious antique weapon from a wealthy man. Once Mal and Saffron are inside, they are discovered, and it is revealed that the man is married to Saffron. Although the man seems initially oblivious, he is aware of Saffron's true nature and called the authorities.

Mal and Zoe receive in the mail the body of Tracey, a comrade-in-arms who fought with them at the Battle of Du-Khang, and they attempt to honor his recorded wish to be returned home. However, a corrupt Alliance officer demands they turn over the body and the goods the soldier was smuggling. While searching the body for clues, they learn that Tracey is still alive and is smuggling organs.

Nandi, an old friend of Inara's and a former Companion, runs an unlicensed bordello on a barren planet. The bordello is frequently patronized by Rance Burgess, a tyrannical ruler who keeps the community excessively poor so that he can govern it as a cowboy. Burgess, whose wife is infertile, believes a pregnant prostitute named Petaline is carrying his child. With Burgess promising to take the child once it is born, Nandi contacts Inara and asks her if the Serenity crew can help defend her establishment. Mal agrees, but upon arrival realizes that Burgess' cavalry is too powerful to fight and advises Nandi and her working girls to leave the planet immediately.

River telepathically hears the crewmembers' innermost feelings. When she picks up a gun in Serenity's cargo bay (which she perceives as a tree branch), the others discuss if she's too dangerous to be kept aboard. Bounty hunter Jubal Early sneaks aboard the ship, intent on claiming the bounty set for River and Simon. Early incapacitates the crew and forces Simon to help him locate River, who has seemingly vanished. While searching the ship, Early recites existential philosophy, claiming to not be evil, simply incentivized to do what is necessary. River's voice appears on the PA system, claiming that River melted and fused with Serenity.
