Der Besuch (2019)

Elise is a timid woman. She’s even afraid of trees. When one day a paper plane sails through her window, she’s so agitated that she hardly sleeps a wink that night. The next morning Emil, a boy in a baseball cap, knocks on her door. He’s looking for his plane and also needs to go to the loo. Suddenly Elise’s life changes in a wonderful way.
