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. But... the greatest danger of all may be on their ship.
