The two half-brothers, Hammer and Hart, return to their hometown of Cologne to claim the inheritance left by their late mother, Roswitha. The two couldn’t be more different: Hammer is from Hamburg, where he runs a boxing club for street kids, while gambler Hart is from Las Vegas. They want to claim their inheritance quickly and head back home even faster. But to their surprise, there’s no money—just “Roswitha’s Car Paradise,” a car repair shop that’s clearly seen better days.
