When the renegade crew of Serenity agrees to hide a fugitive on their ship, they find themselves in an action-packed battle between the relentless military might of a totalitarian regime who will destroy anything - or anyone - to get the girl back and the bloodthirsty creatures who roam the uncharted areas of space.
