During a stopover on her trip to Chile, 31-year-old swimmer Maria (Jessica Schwarz) recognizes a children’s song in Buenos Aires that is foreign to her. Maria doesn’t speak a word of Spanish, but without understanding, she remembers the Spanish lyrics and the melody of the song. Distraught and thrown off course, she interrupts her journey and stays in the foreign city. While she is searching for an explanation, her father Anton (Michael Gwisdek) suddenly appears in Argentina. He confesses to his daughter the truth about her real origins. Maria lived in Buenos Aires for the first three years of her life at the end of the 1970s. When her biological parents disappeared in 1980 as victims of the Argentinian military dictatorship, Maria was adopted by Anton and his wife and brought to Germany.
After the confession, the intimate relationship between father and daughter threatens to break down due to the years of lies, and a path together seems impossible. While Anton wants to return to Germany as soon as possible to let bygones be bygones, Maria wants to stay in Buenos Aires to search for her Argentinian family. The disappointed father fights to the end for the love of his child, the uprooted daughter fights to the end for the truth of her true identity.
