The French national treasure singer Adiot Piaf (Marion Cotillard), known as the "Little Skylark", has a legendary life. Piaf had a wandering childhood, first abandoned by her mother, then sent to a brothel by her father to be raised by her grandmother, and then forcibly taken away to live in a circus after her father retired from the army. After that, Piaf followed her father for a living, sang in the street for the first time and became a young girl singing in a bar. Piaf, who officially appeared on the stage, successfully became a star with a charming singing voice and sang many popular songs. However, her feelings have been repeatedly frustrated, especially with the boxer Marcel (Jean-Pierre Martins). She went from bad to worse in her later years and finally died of liver cancer.
