Barbarella has been lied to. Worse, she's been weaponized, and someone's going to answer for that, for sure. (Well, assuming she survives the judgement of the Esseverine sun-giants, and an armada of a thousand ships...)
Barbarella's never ending quest to repair her ship's regulator and be on her way takes a detour to Falladim, where there's a rush on for R.U.S.T.-Radically Unstable Space-Time! The rarest and most valuable stuff in the universe, even Barbarella can't resist its mighty call. But competition brings out the worst in humans and aliens alike, and the Siren of Space is about to see what the worst really is!
