Penned by Whedon and Brett Matthews, who wrote several episodes of Firefly as well as Dark Horse's final Angel comics series and the animated Chronicles of Riddick feature "Dark Fury," Serenity follows a ship full of mercenaries, fugitives and one law-abiding prostitute in their pursuit for fast cash and a little peace along the fringes of space. The ragtag crew of Serenity take on a scavenger mission with the hopes of earning enough dough to disappear for a while. Only too late do they realize the whole gig is orchestrated by an old enemy eager remake their acquaintance with the help of some covert-operatives known only as the Blue Gloves.
