Vic and Stan reliably carry out assignments and courier services, which may involve the use of forceful arguments. When they transport a seemingly empty suitcase to a bar full of strangely tattooed guys for their boss, they get into a fight and Stan is injured. Later, they both learn that their opponents may have been of demonic origin and were seeking world domination. Vic sides with their opponents, but discovers that Stan has already been infected by the demons.

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.
