During a stopover in Buenos Aires on her way to Chile, 31-year-old Maria recognizes a nursery rhyme.

Disturbed and thrown off course, she decides to interrupt her journey and wander through the unfamiliar city. On the phone to Germany, she tells her father, Anton, about her experience and the peculiar fascination the unfamiliar city has had for her. Two days later, Anton suddenly turns up at Maria's hotel with something to confess: Maria spent the first three years of her life in Buenos Aires during the military dictatorship at the end of the 1970s. The people she had always thought were her parents had adopted her and brought her to Germany. Father and daughter begin a journey in search of Maria's biological parents. Anton does everything he can not to lose his daughter.
