While cleaning Schotty gets a visit from his friends Didi and Frido. A bizarre argument about felt gliders develops, because Didi finds these things strange and has neither time nor desire to deal with such topics, but the time to complain about it. The universe of the felt gliders is almost unfathomable. And so no one gets out of the question of what is actually secondary in life and what is not. But since Didi seems to have a real felt glider problem, Schotty and Frido stand by him and can even help him through a creativity crisis. (thetvdb.com)
