Fresh faced and naïve, 17-year-old Bennie arrives in Buenos Aires to search for his older brother who has been missing for more than a decade. The family had emigrated from Italy to Argentina, but with the great musical success of their father Carlo, an acclaimed symphony conductor, the family moved from Argentina to New York. When Bennie finds his brother, the volatile and melancholy poet Tetro, he is not at all what he expected. In the course of staying with Tetro and his girlfriend Miranda, the two brothers grapple with the haunting experiences of their shared past.
