Ventress had been sent to Coruscant to take probably an attack on the Galactic Senete, where representatives of Bureaucratosis give a speech (which in reality were only grunts and verses), to accompany the sadistic Dark Acolyte was a Separatist droid that could to feel emotions (so much so that could laugh).
Grand Master Yoda sensed danger, and found Ventress, then dueled with lightsabers, while escaping a class of Jedi from the Senate Building with an "infiltrator", Yoda and Cody, a commander of the Republic, imprisoned Asajj, but the droid escaped with some secret battle plans in a book titled Secret Battle Plans.
Later, Commander Cody, Grand Master Yoda and a young Han Solo (posing as "Ian") found and destroyed the droid on Hoth, in the guts of a Tauntaun, saving the plans, while on Coruscant the two fleets of the galaxy battling.
