I'm commenting only because the described synopsis isn't all that fair. This is a movie not about the war, not is it about romance - it's just a story about courage and family, and a very nice one at that.
On the very same day an Austrian and an Italian family are joined in matrimony in a village in the Alps, Italy declares war on Austria, and the men are then forced to serve their nations and fight against each other. The plot is based on how they sacrifice themselves for family, even when they are supposed to be opposite sides. Francesca's relationship with Ander is romantic as much as fraternal, and his attempt to protect her later develops into nothing but the need to do what's right. It's just hardly a center piece, specially when compared to Elisabeth and Angelo and their struggle. I just hope the off synopsis doesn't put anyone off of it, as I did found this a beautiful, sensitive and very enjoyable movie and would definitely recommend it.
