Devilish Honeymoon (Dábelské líbánky) (1970)

A charming senior lecturer Kostohryz (Vlastimil Brodský) is an unquestionable star of the Research Institute of the Chemical Factories, admired by men and loved by women. There are two assistants who furiously compete for his favor - Dagmar (Jana Brejchová) and Ester (Iva Janzurová), whose mutual hatred is almost tangible. The police captain Libícek (Jan Libícek) with his assistant Alzbeta (Jirina Jirásková) can well sense that here life is already at stake.
