A bear and a rat explore dark forests, treacherous ravines and snow-swept glaciers. With no real aim in mind, the bear and the rat bungle along in a folk tale of their own devising, wondering what they should do and where they should go, enjoying nature together, foraging for sustenance, getting lost, squabbling, joking and making music along the way.
In 1881 Ludwig of Bavaria goes on a cruise on a Swiss lake. He takes with him a famous actor, Josef Kainz, to act out the scenes from a story which took place on the lake, at the actual locations.
In this docudrama, the real star is a railroad tunnel. First built, at the instigation of a banker and an engineer, in 1872 under appalling conditions, it was widened to accommodate automobiles in 1972. The tunnel links the Rhineland in Germany with Italy and goes through the Swiss mountains. The many lives lost in the building of the first tunnel were considered to be one of the costs for economic progress. In one re-enactment, a strike for better conditions is severely dealt with by the military. Even in 1972, though working conditions were better, most of the men working on the tunnel were poor immigrant workers, with almost no power to negotiate better treatment.
