A Slovak detective story set in contemporary Bratislava and featuring ordinary people with their own everyday problems. The violent death of Olga Holešová places them under heavy suspicion of murder. A series of strange coincidences and circumstances complicate the investigators' work. Her husband's infidelity, the loss of a large sum of money that the treasurer Fiala is supposed to replace, a lawyer earning extra money by doing various odd jobs - all these are confusing clues, among which investigator Jakubec eventually finds a thread that will lead him to the correct solution to the case.

A dramatic story about two friends - fisherman Richardus and municipal executioner Emil Targo takes place at the river Danube, in places that used to be targets of Ottoman raids. But their attraction to the same woman and Emil’s betrayal change their indissoluble friendship to an equally strong hatred. And as it usually goes - after twenty years by a trick of fate Richardus’ daughter Agajka becomes the wife ofthe sun of his sworn enemy.

In Slovakia, they also created a pair of investigators who have appeared in several films. Volanie démonov is the third of them. The police officers, one Maigret-like, thoughtful, the other humorously hasty, this time solve a fire in a furniture factory and the deaths of two employees - one burned himself, the other fell into a dry well. The investigation of the complicated case takes a long time, but in the end it turns out that revenge can be extraordinarily strong and persistent.
