Maia, a single mother, lives in Montreal with her teenage daughter, Alex. On Christmas Eve, they receive an unexpected delivery: notebooks, tapes, and photos Maia, from 13 to 18 years old, sent from Beirut to her best friend who left for Paris to escape the civil war. Maia refuses to open the box or confront its memories, but Alex secretly begins diving into it. Between fantasy and reality, Alex enters the world of her mother’s tumultuous, passionate adolescence during the Lebanese civil war, unlocking mysteries of a hidden past.

In the fifties, young Alice leaves her natal Swiss mountains for the sunny and vibrant shores of Beirut. She falls madly in love with Joseph, a quirky astrophysicist intent on sending the first Lebanese national into space. Alice quickly fits in among his relatives, but after years of bliss, the civil war threatens their Garden of Eden.
