Somos Renáta , also known as Reni (Kata Gáspár), is a single mother of three children who, despite her IQ of 160, works as a cleaner. By chance, the police recognize her potential, so the head of the life protection department, Major Anikó Cseke (Móni Balsai), offers her a job as a consultant, which Reni accepts only if in return they also help her solve the biggest mystery of her life.
