Four avid artists live a calm life, but whether this life can be called calm is another question, because they are in such a “wonderful” place as the Old Town, where you never guess whether summer or winter will come tomorrow. But this is not what we are talking about now. The artists are going about their everyday business, but apparently they have greatly disturbed someone, because now, wherever they go, something strange is constantly happening to them: they want to poison them with with the help of ordinary sugar, then in the closet they find a secret corridor ending with a large wooden door, and they absolutely had to find out what was behind it! But the main thing, perhaps, was that someone was constantly watching them and wanted to catch them.
