Summary
Mal is sitting, naked, in the desert. Something went well. Mal is sitting, naked in the desert.
I'm pretty sure there's something else in this episode, but I can't really remember what.
Oh yes, so. Mal is sitting naked in the desert. Flashback takes us back to find out why Mal is sitting, naked, in the desert.
The whole episode recounts how Yo-Saff-Bridg, aka Mrs. Reynolds, drags the whole crew into yet another petty crime. True to herself, she betrays everyone and Mal especially. Betrayal leads to stripping, and stripping leads to Mal, sitting naked in the desert.
Inara and Zoe both have nice moments of revenge in this episode.
Meanwhile, Jayne, Simon and River don't really care about Mrs. Reynolds and have various chats about betrayal, trust, girl's names, men's parts, and how a brain can kill.
At the end of the episode, Mal gets back to Serenity, still naked. That was a good day.
