For me, it sounds as familiar story. A box with old memories is delivered to a venerable lady who, first, refuses it. The box containes diaries and photos from the early ages of her daughter , composing, like pieces of puzzle, Lebanon war, family relations, first romance, the death of father, all covered by the refuge in Canada.
The daughter of recipient, a teen girl, explores, secretly, this treasure, discovering a past unknown of her mom.
A trip at Beirut seems good frame for reconciliation between them and, in same measure, the reconciliation with past of mother.
Indeed, for many motives, a beautiful film. Seductive, touching, well crafted, nostalgic, melancholical.
Its virtue- science to suggest and fair steps of confrontation, in some measure, in poetic manner, with past.
