The four brothers Peter, Uwe, Manni and Günter live together in the German town of Dernbach and run what is probably the most chaotic car recycling business in Germany. Nothing is the same here as in other junkyards. Over four million spare parts lie in huge piles in the brothers' warehouse. Nevertheless, they manage to find just the right spare part time and time again and get a car back into shape.

In Cologne, a park bench ends up in the Rhine and floats with the flow - until one day it finally ends up in Langeoog.

The three friends make it their mission to find the original owner of the bank.
