Season: 1

Hard up for cash, Serenity takes on a job from Simon: help him get a thorough diagnostic of River in return for the opportunity to loot the vast medical stores of an Alliance hospital on central world Ariel. But River's pursuers are hot on their trail, and they receive some unexpected inside help.

Mal must choose which crew members to save when one is gravely wounded and two others are kidnapped. Simon finds an uneasy haven in a remote village, but River's uncanny perceptions jeopardize the Tams' temporary safety.

Inara attends a formal society dance, only to find Malcolm there as well, attempting to set up a smuggling job. Mal comes to blows with Inara's conceited date and finds himself facing a duel with a renowned swordsman, and only one night to learn how to fence.

After Serenity suffers a catastrophe that leaves her crew with only hours of oxygen, flashbacks show how Mal and Zoë acquired Serenity and assembled their motley band.
