Isabelle is an astronomer of French origin who lives in Italy in a large house surrounded by vineyards in the hills near Trieste. The sun shines on the countryside, the sea breaks on the rocky coast a few kilometers away, the landscape is paradise, and like every summer, her son Jérome will spend some time with her. Isabelle loves him very much and is ready to do anything for him, but her encounter with Davide, a young man going through a very difficult time, will turn their lives upside down. Isabelle will then have to make a choice that will inevitably lead to a painful outcome.
