The story takes place in the Italian Riviera in the 1980s. Every summer, 17-year-old Elio (Timothe Chalamet) comes here for a holiday with his family. This year, they shared their holiday time with Oliver from the United States (played by Amy Hammer Armie Hammer). The tall, handsome, warm and cheerful Oliver soon won the love of Elio's family. With the passage of time, there is a fatal attraction between Elio and Oliver, but the shackles of gender and age make it impossible for them to take that crucial step. At the same time, the simple and kind girl Machia (Esther Galle Esther Garrel) also dedicates her feelings and body to Elio. In the end, the surging passion broke through the line of defense between Ario and Oliver, and the two began a relationship that was destined to come to an end.
