The swiftest path to destruction is through vengeance. Darth Sidious orders Count Dooku to eliminate his apprentice, Asajj Ventress. Ventress survives Dooku's assassination attempt, and flees to the planet of Dathomir to enlist her kinswomen - the mystical Nightsisters - to assist her in a campaign of vengeance against her former master.
