The Birch Wood (1970)

Takes place in a prewar Poland. A tubercular young man comes to stay with his brother on a farm. He is in love with life and constantly plays 1930's music on a piano. He gets involved with his brother's problems and also becomes the lover of a simpleminded farm girl. The brother's dead wife may have had an affair with the hired man who is to marry the farm girl. His daughter will not confirm his suspicions. But the brother's death leads to his acceptance of the past, forgiving his wife's memory and making up with his little daughter.
