Serenity continues to travel through space conducting illegal runs across the star system, which is under the control of The Alliance. A powerful and fearsome mobster named Adelei Niska demands that the crew of Serenity pull a train robbery. The train is carrying medical supplies for a community, and Reynolds and Zoe get held on suspicion. They get free with Inara's help but realize they were tricked and try to return Niska's money. His henchman isn't too happy, but Mal "persuades" the next guy to take the money back. Meanwhile, two blue-handed, black-suited operatives close in on River.
