Alarming rumors about the peace-abiding Duchess Satine of Mandalore prompt Obi-Wan to investigate the secluded planet. Satine wants to keep Mandalore neutral in the Clone Wars, but the actions of a violent splinter group -- Death Watch -- threaten to push the planet towards war.

On Coruscant, word reaches Duchess Satine that Death Watch is mobilizing, sparking a pre-emptive Republic invasion. On the run from Republic authorities, Satine and Obi-Wan set off to discover the group's true motives.

Ahsoka is assigned to teach a class at a leadership academy on Mandalore. Soon after she arrives, Duchess Satine's zealous nephew -- Korkie -- and his classmates uncover a nefarious plot. Prime Minister Almec is revealed to be an active part of the black market conspiracy on Mandalore, and he attempts to permanently silence Duchess Satine and the cadets before they expose his corruption. Ahsoka and the cadets defeat Almec before he can succeed.
