Watch Fmovies. A theater competition breaks out on the occasion of the four-year anniversary celebrations at the Hennigsberg power plant. The old hands want to perform the kitschy musical comedy "Gärtnerliesl". The youngsters are against it and are planning their own program with which they want to skewer events from the plant in a cabaret style. But first, everyone has to work together on a turbine breakdown. On the day of the festival, the "Gärtnerliesl" fails with timpani and trumpets, while the youth's program is met with great applause, which the rivals join in with.
