In Sacco City, a bustling immigrant-filled metropolis, the terrorist group Optimums has imposed strict control since taking over a year ago. They've introduced harsh laws and reclassified immigrants from the Far East as East Refugees.
He Jiang, a quick-tempered young woman, works alongside her father He Chang Feng, driving their truck to make deliveries across Sacco City. One day, the Klee, a paramilitary police unit, arrests them for transporting a sword. During the confrontation, He Chang Feng is killed, and He Jiang is sentenced to eight years in prison.
After her release at age 24, He Jiang, with help from new friends, retrieves and fixes their long-abandoned truck. Resuming her delivery work, she encounters many obstacles, including discriminatory policies from the Department of Security targeting East Refugees like her. Determined to resist, He Jiang realizes she will need more allies to succeed.
