It was a Sci-Fi series set in kind of a Western theme. The main characters were smugglers and bandits of a sorts, living in the systems outside the primary control of the ruling alliance. 2 of the main characters fought in a civil war some years before to challange the formation of the alliance, but lost. The ship they fly in is Firefly class. They have a prostitute living aboard, although its a respected profession in that culture (to those who are trained and certified, which she is). The series also had a priest riding with them as a "passenger", but I don't recall seeing him in the trailer. My favorite character was always Wash. On a slightly wierder note, a common language in this future culture is Mandarin, so they sometimes utter words in that language. They usually curse in it or exchange angry words in it, though no subtitles are provided. Its up to the viewer to either A), know Mandarin (and get past the accent), or B), infer what was said by the subsequent reactions.
