In the city of Sacco, ruled by the oppressive Optimums, a young woman named He Jiang navigates life as an immigrant alongside her father, He Chang Feng, in their truck. Their world is upended when the Klee, a militant police force, arrests them for possessing a forbidden sword, leading to tragedy as He Chang Feng is killed, and He Jiang is imprisoned for eight long years. Upon her release at 24, He Jiang, aided by newfound companions, resurrects her old truck to resume her deliveries in a city burdened by discrimination. Faced with challenges from the biased Department of Security and the oppression against East Refugees, He Jiang must rally more supporters to challenge the status quo and fight for justice.
