In the middle of a routine shopping trip on Coruscant, C-3PO is abducted by the bounty hunter Cad Bane. Bane is looking for information about the Senate building on behalf of Jabba the Hutt. Finding C-3PO devoid of useful information, Bane and his accomplices kidnap R2-D2 and extract the vital data, before memory-wiping the droids of the incident, and letting them on their way. The floor-plans and security details of the Senate building are part of a plot engineered by the Hutt families to free their imprisoned brother, Ziro the Hutt, who holds potentially damaging information about Hutt activities.

Cad Bane has broken Ziro the Hutt out of prison. The Hutt Council demands that Ziro tell them where he's hidden vital -- and incriminating -- information: a journal detailing the criminal activities of the Hutt families. Ziro makes another daring escape with the help of his estranged (and strange) lover, Sy Snootles. Bane is back on the Hutt's trail -- but he's not the only one. The Jedi Obi-Wan Kenobi and Quinlan Vos need to find him too. A chase through the swamps of Nal Hutta leads the pursuers to Ziro's enormous mother, Mama the Hutt, who points them to Teth. It is here, in the secret grave of Ziro's father, that the fugitive Hutt has hidden the diary. When he retrieves it, Snooty reveals her true spots. She's a deadly woman scorned and a bounty hunter for hire!
