What starts out as a nice day at a space station goes very wrong when Mal and Zoe receive the corpse of their old war buddy in the mail.
Mal has to make a tough choice in whether he should trust Saffron when she offers the Serenity crew an opportunity to make a lot of money on a risky job.
Tensions begin to run high on board the Serenity when Wash finds himself feeling threatened by the closeness between Mal and Zoe.
On return to Ariel, Simon hires the crew out to smuggle River into a hospital so Simon can figure out what the Alliance did to her.
The Serenity engine explodes, leaving the crew low on oxygen and adrift in deep space.
