From IMDB:

In 1980s Italy, a romance blossoms between a seventeen year-old student and the older man hired as his father’s research assistant.

British Airways offered this film with subtitles. In fact, there is a mixture of languages.

In the book by André Aciman as I recall, correct me if I am wrong, there is no sexual contact between Oliver (played by Armie Hammer) the older assistant and Elio (played by Timothée Chalamet) the teenage son. But this supposed screen adaptation shows almost explicit sexual activity. In one review I read, the critic complained that the film could be seen as condoning Oliver’s self-interested grooming of the young, inexperienced Elio. So you must do at least three things: forget the book, prepare yourself emotionally for the scenes, and decide for yourself what you really think about Oliver’s behavior. 

Evocative portrait of a small setting in northern Italy, but quite possibly not to everyone’s taste.
