In a prestigious health center for wealthy women, strange things begin to happen: sometimes there are nails in the massage sponges, sometimes there is paint that doesn’t wash off well in the mud bath, sometimes there are dead carps in the jacuzzi, sometimes there are live worms in the bowl of yogurt. Is this not a clear attempt to discredit and ruin a thriving establishment? And who might be interested in its collapse - an envious person or a competitor? The famous detective Hannah Wolf takes on the investigation, not without pleasure, because it’s not often that you have to look for a criminal in a corner of paradise, where you are pampered with massages, therapeutic masks and aromatic baths.
