Blau blüht der Enzian

Blau blüht der Enzian (1973) is a comedy directed by Franz Antel rated 8.5/10.

The students at a school of hotel management repurpose the institute into a hotel with a show stage, double-cross the principal, the groundskeeper, and a grumpy millionaire, and cause so much mischief and confusion that, in the end, there is only one thing left to do: laughing to the bitter end!
