Fischkopp Henning can't really do anything. Apart from making slogans and picking up women. When he has to deliver a strange package from Hamburg to Munich, there's plenty of opportunity to put his talents to good use.

Inge, a chemist in a small Bavarian town, has lost her heart to Hub, a car mechanic, without him even suspecting it. For the time being, Inge doesn't want Hub to find out about her.
