In the first few episodes, Franz Meersdonk (Manfred Krug) is a trucker working for the Munich-based company, "Mittermann Haulage", driving mostly the Germany-Iran route.

Franz gets to know a washed up racing driver, Günther Willers (Rüdiger Kirschstein) and talks him into teaming up for the new assignment.

Once an insurance fraud is cleared up in a later episode, they finally get the money together to form their own company: International Transport in Munich.

Most of the episodes involve auto theft, cargo scams, dubious acquaintances, or smuggling.

Early in the series, when the action was set in a foreign country, the actors spoke their own language and no subtitles were provided, so that the viewer would experience the same communication problems as Franz and Günther.
