André Gil Mata - The Tree AKA Drvo (2018)

A man, a child, two wars, a river, a tree. A man and a child meet under a tree on a river bank, sharing the same memory and a secret. They find in each other the serenity, the silence and the time they lost in the flowing water of the river.

One of those rare films so accomplished and yet so open to interpretation that each viewer will find their own references.
