Pure outlaw racing in a wrecked world, with nightmare custom vehicles built from scrap and terror. A young woman determined to escape her father's shadow builds Iron Duke, a rebuilt 1991 GMC Sonoma S15 with a five-speed manual, swapped V6, turbo, and extensive performance modifications. It sleeps through the day as an unremarkable truck, then becomes a legendary night racer, built for drifting, drag, circuit racing, and sprints. By day, its driver works as a delivery driver and diner cashier. There are no weapons, only drivers, machines, speed, and dangerous roads.
