On the prairie in eastern France, fans of country music and culture are having fun in the dance rhythms of a cowboy festival. Alain (François Damiens) comes on stage and sings the song "The Tennessee Waltz", and then has a dance with his 16-year-old daughter Kelly in front of his wife and son Kid (Finnegan Oldfield). He does not know yet that this is the last dance they have had. The very same day, Kelly disappears. Alain thinks his daughter has been kidnapped. It turns out, however, that Kelly converted to Islam and fled with her boyfriend, a Muslim Ahmed, to live a life following the principles of the Quran. Alain cannot accept the decision of his daughter. Although in the letter she left, Kelly asks the family not to look for her, Alain sets off on a quest to find her, leaving behind everything he had loved.
