Der Kaiser (2014)

When little Kai watches his father come home after a five-year prison sentence, he meets the most important man in his life. But he does not have that many memories of him. Hiding behind a mask, he only sparsely lets him and the surrounding world in. Gradually, the need of fatherly love outdoes the confusion about who his father is and why he was gone. A big reunion in a small film.

Unfortunately the movie Der Kaiser is not yet available on HBO Max.
