Firefly: The Train Job

"The Train Job" is the second episode of the American science-fiction western television series Firefly created by Joss Whedon, although it was the first to be shown. (The pilot, "Serenity", was not shown until nine other episodes had been aired.) According to the DVD commentary, Whedon and Tim Minear had only two days to write the script. The crew of Serenity take on a hovertrain heist commissioned by a sinister crime lord. The cargo they are after, however, is worth more than they know.
