Its a day like any other for amateur athlete Herr Herrmann Mann – his wife Frauke Mann is rampaging once again. With “little night music” by Mozart playing on his Discman Mr. Mann hastily puts on his running shoes and flees into the nature. At the railway crossing in the forest he can take a short breather in front of the closed barriers. Suddenly he realizes why Frauke was so furios: He forgot her umpteenth wedding anniversary.
