A three-year-old girl, Marta, disappears without a trace from her home on the same day when the German army withdraws from her town in the spring of 1945.
Fifty-seven years later, Marta's cousin Vesna is determined to solve the mystery of the missing girl's fate. A promotion offer and a new job lead Vesna to Frankfurt—the city where she believes Marta may have ended up.
However, solving the little girl's mystery is challenging, knowing only the first names of the girl and her abductor.
While Jona Weber, a private investigator, digs into the city's historical records, Oliver and Walter, Vesna's new colleagues, provide essential help in finding her cousin. Are they just colleagues, or is there a deeper connection between them?
As the family delves into the investigation, they stumble upon a much larger mystery that leaves them all stunned.
