After the brilliant disclosure of the zombie case in the secret department where the Crusaders serve, they create a special unit of the COPROD - a Special department for the investigation of occult affairs. The group faces a new challenge: to deal with a witch's curse that has ruined an entire family. And while Crusaders and Masha are interviewing witnesses, Morozov, without the knowledge of the leader, goes to the witch herself, who brings corruption on him...

A series of strange deaths are taking place in the new Karpaty country hotel. Rumor has it that this is how the curse of the past inhabitants of this place, Romanian vampires, works. One of the victims was stabbed in the heart with an aspen stake... The Crusaders, as Konstantin's team is called in the department, go to the hotel: Masha gets a job as a maid, and Morozov settles there under the guise of a tourist. Meanwhile, Crusaders are haunted by his long-time enemy Faust, who invisibly monitors the work of the department.
