The assaults grow heavier on the remnants of the Republic forces on Troiken and the fragile defense falls increasingly to Plo Koon. Can Qui-Gon Jinn find the secret of the virus that has corrupted the Republic nav computers and open up the hyperspace lanes to the Republic again? Meanwhile, Tholme and his apprentice, Quinlan Vos, struggle to get what they've learned back to the other Jedi.
