The year is 1998. At a country festival in the country in France, Alain and his teenage daughter Kelly stand on stage and sing the melancholy "Tennessee Waltz". This will be the last time Alain sees her daughter - soon after she is gone. At home, her parents find a letter from her: She has run away with her boyfriend, a Muslim boy, and asks them not to look for her. The father is convinced that she has been abducted against her will. Obsessed with the desire to find her, he embarks on a journey that takes him to Yemen and Syria - without result.
