Well, who would have thought what a minor quarrel between the Efimov spouses would lead to? Out of nothing! And the result is deplorable: four sleepless nights and four restless days, during which the Efimov couple, together with Irina’s friend Natalya, were not only witnesses, participants, but also hostages of incredible, frightening events. It all started with a forced trip by surgeon Efimov to his former patient Stanislav Poletaev. A series of troubles awaited along the way. A strange person discovered in the swamp, the suspicious hospitality of the Poletaevs, the gathering of Stas's relatives on a false call and their constant scouring the house in search of money and jewelry added to the mysteries. And the main factor of horror is a series of accidents with the inhabitants of the cottage. What happened would be scary if... it wasn’t funny.
