Serenity (movie) Synopsis
The crew leaves 'Serenity' and finds a place to fight off the Reavers while Mal goes to get to Mr. Universe and send the message. Mal finds Mr. Universe has been killed and his equipment is destroyed. He finds a message that tells him about a hidden backup transmitter. The Reavers attack the crew, and make them move back. The crew tries to close a blast door, but it will not shut all the way. River dives through the hole in the door and closes it from the other side. This traps her with the Reavers. Mal gets to the other transmitter. The Operative gets there also and they fight. Mal wins but does not kill the Operative. He leaves him to watch the video from Miranda as it is being broadcast.
