Alfredo and Luigi grew up in Valsesia, in northern Italy. Their father planted trees for them when they were born- for Luigi, a larch, which looks towards the sun and waves in the wind; for Alfredo, a fir, which flourishes only in the shade. Since their father's untimely death, all the two brothers have in common is their heavy drinking and the old family home, high up on the mountain. Luigi would like to buy Alfredo out, move from down in the valley to start a new life up in the heights with Elisabetta and the baby girl they are expecting. But in this remote and wild landscape, one drink too many, one wrong word, can turn dogs into wolves.
