Oliver & Elio

It is the summer of 1983. Elio, a 17-year-old Jewish Italian, lives with his parents in rural Northern Italy. Elio's father, a professor of archaeology, invites a 24-year-old graduate student, Oliver, who is also Jewish, to live with the family over the summer and help with his academic paperwork. Elio, an introspective bibliophile and a talented musician, initially thinks he has little in common with Oliver, who appears confident and carefree. Elio spends much of the summer reading, playing piano, and hanging out with his childhood friends, Chiara and Marzia. During a volleyball match, Oliver touches Elio's back as a sign of interest but Elio brushes it off. However, Elio later finds himself jealous upon seeing Oliver pursue Chiara.

Elio and Oliver spend more time together, going for long walks into town, and accompanying Elio's father on an archaeological trip. Elio is increasingly drawn to Oliver, even sneaking to Oliver's room to smell his clothing. Elio eventually confesses his feelings to Oliver, who is awestruck and tells him they cannot discuss such things. Later, in a secluded spot, the two kiss for the first time. Oliver is reluctant to take things further and they do not speak for several days.

Elio goes on a date with Marzia and the two have oral sex. Elio leaves a note for Oliver to end their silence. Oliver writes back, asking Elio to meet him at midnight. Elio agrees and they sleep together for the first time. In the immediate aftermath, Oliver says to Elio, "Call me by your name and I'll call you by mine." The morning after, Elio is briefly conflicted about their encounter and takes out his sexual frustration by masturbating with a peach. He cries about how little time he and Oliver have left together. Marzia confronts Elio after not hearing from him for three days. He offers a cold response, leaving her heartbroken.

As the end of Oliver's stay approaches, he and Elio both find themselves overcome by uncertainty and longing. Elio's parents, who are privately aware of the bond between the two but do not address it openly, recommend he and Oliver visit Bergamo together before Oliver returns home to the U.S. They spend three romantic days together. Elio, heartbroken after Oliver's departure, calls his mother and asks her to pick him up from the train station and take him home. Marzia is sympathetic to Elio's feelings and says she wants to remain friends. Elio's father, observing his deep sadness, tells him he was aware of his relationship with Oliver and confesses to almost having had a similar relationship in his own youth. He urges Elio to learn from his grief and grow, instead of just moving on too quickly.

During Hanukkah, Oliver calls Elio's family to tell them he is engaged to be married. An upset Elio calls Oliver by his name and Oliver responds with his, he also mentions that he remembers everything. After the call, Elio sits down by the fireplace and stares into the flames, tearfully reminiscing, as his parents and the house staff prepare a holiday dinner.
