The story of two friends — employees of the investigation department of high-profile crimes of the Investigative Committee. The authoritarian, bright Irina Makarova, the "self-made woman" of post—Balzac age and the quiet, painfully withdrawn, very young general's daughter of Dean Voloshin - they were entrusted with a joint investigation into the murder of women with special cruelty. Ritual murders take place in different parts of the city — obviously, it was done by one person, a complete psychopath. They will catch him because they are "abnormal bitches" themselves, according to representatives of the male part of the department staff.
