The serial killer Zhanna Dronova,
nicknamed “Female Mantis”, is serving
a sentence in a high security prison after
admitting eight especially cruel murders.
Zhanna killed only men — pedophiles,
rapists, domestic abusers, and unfaithful
husbands. When she finds out that
she has a copycat, the woman offers
the police her help, under two conditions.
First: she will leave the colony for
the period of the investigation. Second:
her son Denis will be involved, who has
not communicated with his mother for
the past 20 years.
