In 2014, Dr. Ruja Ignatova (Nilam Farooq) founded "OneCoin," a new cryptocurrency that quickly became a growing empire in the global financial world. Three years later, the crypto queen vanished with tens of billions of dollars after defrauding countless investors. Her lover and business partner, Sebastian Greenwood (Charlie Petersson), and her other lover and main money launderer, Gilbert Armenta (Mads Korsgaard), were both arrested. While her daughter Gemma grew up in Frankfurt am Main with her father, Jonas Kurth (László Branko Breiding), without her mother, international law enforcement agencies like the FBI, Europol, and the German Federal Criminal Police Office (BKA) relentlessly pursued Ruja – but then her trail went cold. To this day, the world's most wanted woman remains missing.
