Teenager Elio (Timothée Chalamet) is spending the summer with his family in the Italian countryside. Whiling away the hours only takes up so much of his time, but when he catches the eye of Oliver (Armie Hammer), an older student working with Elio's dad for the summer, the teen falls hard and fast. The pair have a sexy yet slightly questionable love affair for the summer, finding pleasure in the taboo nature of their relationship. For Elio, though, this big love means everything. To Oliver, however, this is just another blip on his radar, and in the end, both call into question the decisions they've made.
