When the renegade crew of Serenity agrees to hide a fugitive on their ship, they find themselves in an awesome 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.
Five short vignettes, sequenced out of chronological order, depict excerpts of counseling sessions between River Tam, played by Summer Glau, and her unnamed therapist, played by Whedon, while she is held at the Alliance Academy.
