Plot

A house by the lake, very close to Berlin: this is where former hit star Arthur Weyer, 75, and his wife Elsa, who is ten years his junior, spent many happy hours. But that is a long time ago. The couple separated four years ago - Arthur had fallen in love with a much younger woman. This relationship failed since Arthur fell ill with dementia. Despite all the bitterness, Elsa still feels responsible for Arthur and is looking for a place in a nursing home. In order to be able to finance this, the house on the lake has to be sold - but against Arthur's will. For the clearing out and repairs, the two hire Sorin, a 45-year-old man who lives alone on a houseboat and earns his money as a DJ and with odd jobs. Because of his Eastern European heritage and lifestyle, he is "the stranger" to the area. Sorin and Arthur hit it off right away, play the piano together and even do chores around the house together. This displeases Elsa and initially there are heated arguments between her and Sorin. But slowly Elsa and Sorin are getting closer. Suddenly things are brought up that have been suppressed for years or no longer seem relevant - injuries, but also happy memories. It becomes increasingly clear why Elsa still cares for Arthur but often seems distant, and why Sorin lives alone and seeks solace in alcohol. The meeting of the three people changes a lot - and leads to drastic decisions.
