Tage im Hotel is a German film directed by Ulrich Stein [de].
After a three-year stay abroad in the United States, young Gernot returns to Germany with his girlfriend Kathy, whom he met during his time there.
In the film, the character played by Sarah shoots her boyfriend's best friend when she thinks he wants to approach her sexually.
Unlike Kathy, Gernot remains undecided and continues to spend most of his time in his hotel room.
He calls Sarah to meet her and spends some time talking about the world's problems with fellow hotel guest Christoph Liedloff.
