With help from R2-D2 and a squad of captured battle droids, an elite team of Jedi and clone troopers led by Obi-Wan and Anakin attempt to free a captive Jedi general, Even Piell, from an impenetrable prison. Despite orders to the contrary, Ahsoka Tano tags along, though she proves indispensable when the infiltration mission begins to evolve. Piell and his fleet officer, Captain Tarkin, are liberated from their cells, but now the fugitives must escape the Citadel itself.
