A battle for control of the craft threatens to erupt after Mal and Zoe become entangled in a botched mission to steal medicine from a moving train.
The episode opens in a dark, musky bar on Unification Day - the day celebrating the final victory of the Alliance, giving them control of all the settled worlds. Zoe and Mal are playing a game while Jayne watches. Of course there is a loud mouth who has to badmouth those who fought in the war against the Alliance (such as Mal and Zoe), and the inevitable fight ensues. The bar brawl ends up outside with Wash bringing Serenity over for a last minute rescue along the edge of a cliff.
Looking for work, Mal, Zoe and Jayne meet a man named Adelai Niska with his resident henchman Crow. Niska has a job for them - a train job stealing the cargo from a passenger train. As it's supposedly Alliance goods, Mal has no problem, but when he finds out the 'goods' are actually medicine needed for Paradiso residents who are suffering from Bowdens Malady, Mal must decide whether he wants to get paid and possibly be responsible for the death of miners and their families or return the cargo and face the wrath of Niska.
THUG: I'm thinkin' you're one a' them Independents.

ZOE: If you die, can I have your share?
KAYLEE: There's no call to be snappy, Jayne.

JAYNE: These are stone killers, little man. They ain't cuddly like me.
RIVER: Two by two, hands of blue. Two by two, hands of blue.
MAL: Whatever happens, remember I love you.

In the sick-bay, two clipboards(approve sites) are visible on the wall next to River. The word "Oakton" is legible on the bottom of one. Apparently some Earth-that-was companies still exist in the future. :)
