A wallet follows the financial weal and woe of an average (West) Berlin family of three on an average income. A cheerful, satirical look at everyday life in 1960, the Schulze family lives in an apartment building somewhere in (West) Berlin in 1960, with father Erwin, mother Dorette, their adolescent son Männekin and dog "Nauke". A small family in which, as in all families, there is sometimes more, sometimes less harmony. Money is always a point of discussion. When Erwin brings it home at the end of the month, Dorette divides it up precisely for the coming month in a recurring ritual.
