Leaning (2014)

A lonely house. A woman is treating her little garden, around her just an heavy winter sky and a small radio that broadcasts the news of some terrible serial killings committed in the area. And while in the house two little girls plays quietly, a menacing figure is about to arrive and upset this quiet, little place; his eyes are full of madness and the clothes he wears shows how Evil can hide behind the most harmless and reassuring appearance.

Unfortunately the movie Leaning is not yet available on HBO Max.
