When I rented this movie, the movie-renting-woman asked me whether I had seen any other movie from this trilogy before. I said, yes, blue. And that I had liked the athmosphere. Yeah, she said, no wonder, I mean, it's not like you could tell their plot.
Let me try: Karol, a Polish barber, gets thrown out by his French wife in Paris because he cannot satisfy her sexually. Wow. As he is blowing the comb in the metro, Mikolaj picks him up. Mikolaj takes Karol to Poland in a suitcase
because he wants to die and cannot do it himself, he wants Karol to help/kill him. Karol then makes a lot of money and stages his own funeral. He wants his ex-wife to come and the only way he can think of to make her come is by bequeathing her a lot of money. She comes, they have extraterrestrial sex and possibly live happily ever after (the movie ends before that).
If you were wondering whether Karol killed Mikolaj: No, he didn't. The first shot was a blank cartridge and while Karol was crying, Mikolaj began to want to live again. Seemed like the theatrical radicalisation of something I talked about with Rieke the other day: How much you can approve and love a decision of yours when you were almost completely sure before that you would do just the opposite, which you had all thought through.
