The stormtroopers of the 407th division, Anson Trask, Sergeant Harkas, Jes Gistang, Hondo Karr, and Vax Potorr are sent to take down one of their own. The 908th division is going to defect to former Emperor Fel's side against the current Sith regime. The 407th is ordered to stop them, and Sith Lord Maleval joins them to ensure they finish the job. Trask's first mission as a stormtrooper challenges his ideals as well as his courage and has dire consequences for the rest of "Joker Squad" as well.
