Five years after the Great Jedi Purge and the Galactic Republic's conversion into the Galactic Empire, former Jedi Padawan Cal Kestis is hiding on the planet Bracca, where he works as a scrapper salvaging ships from the Clone Wars. After Cal is recorded by an Imperial Probe droid using the Force to save his friend Prauf, two Inquisitors known as the Second Sister and the Ninth Sister are sent to investigate.
