The TV thriller "Without a Trace - The Case of Nathalie B." tells the true story of Nathalie Birli, a young mother and triathlete who manages to escape alive from the hands of a brutal and insane kidnapper. A story that made waves in the international press, including the New York Times, BBC, Sun, Bild, Spiegel, and more.

The 26-year-old triathlete Nathalie Birli (Luise von Finckh) is eager to get back into sports three months after the birth of her daughter. She sets out on her racing bike for a training ride, while her husband Martin (Stefan Gorski) takes care of their child at home. Initially unaware of a car following her on a mountain road, Nathalie suddenly realizes when there's a collision, a fall, and an exchange of words with the driver (Dominic Marcus Singer) – leaving her unconscious! Concerned after Nathalie hasn't returned home after two hours, her husband becomes restless. However, the local police dismiss his missing person report. Martin believes every minute counts and initiates a large-scale search. Meanwhile, Nathalie regains consciousness, only to realize with horror the danger she's in.
