Plot synopsis: In a small Saxon town after the Second World War, the former chimney sweep Toni tries to survive on the black market and meets the pusher Ginfizz. Together they initially trade in flour before embarking on a riskier plan: they are to rescue machines from Soviet expropriation for the mill owner Hartmann by transporting them in hidden trucks. In the process, they become entangled in various adventures, from rescuing orphans to transporting pigs, while being constantly pursued by the young policewoman Gisela, who wavers between her professional duty and her attraction to Toni. After Ginfizz is caught and the others remain temporarily free, they help to get the mill up and running again to avert a food shortage.
