The father has always had a beard, the son really only knows him wearing one. That's why he asks questions such as why do men have beards? And what does the beard mean? Here the documentary starts. During the film he discovers by doing interviews and searching for information, that the answer might not be so straightforward.
In the second documentary by Sebas van den Brink, he searches for the real reason why his father has a beard. For many it's an aesthetic consideration, but for his father it's the expression of a wish for something else entirely.
