Anakin gets a padawan, Ahsoka, assigned to him by Yoda. With Obi-Wan, they
have to go and retrieve Jabba the Hutt's son who has been abducted by an
unknown party. An alliance with Jabba is of utmost importance, since he
controls the routes in the Outer Rim, and therefore decides who will lead the
war there. Anakin and Ahsoka lead a commando operation to retrieve the baby
Hutt, while Count Dooku makes Jabba believe that the Jedis are the one who
abducted his son. Anakin and Asoka manage to escape from the ancient monastery
where the baby was held prisoner, while Obi-Wan fights Dooku's assassin who
was supposed to retrieve the baby and return it to Jabba in order to prove
they are on his side. Meanwhile, Padmé meets Jabba's uncle on Coruscant and
discovers that he's an accomplice of Dooku, and had helped him kidnap the baby
in exchange for the control of the Hutt clans. Ahsoka and Anakin finally
manage to return the son to his father, and the treaty between the Republic
and the Hutt is secured.
