According to the filmmakers, "Mad Heidi" is a swissploitation film where all imaginable Swiss heritage, particularly cheese, is exploited in the worst ways, mostly leading to bloody mayhem.

As an independent project financed by fans, the film boasts remarkable technical and artistic craftsmanship. However, it seems to lack the touch of a visionary director capable of elevating the source material. Especially during the sparse action sequences, everything seems to resolve in only a few shots, often resulting in anticlimactic moments, as if they realized they didn't have enough footage only in the middle of the editing process.

The trailer captures all the best moments in just a few minutes, leaving the rest of the film with a lesser impact than expected.
Nonetheless, I’m up for any sequel.
