A man with long braids and an Indian feather in his hair steps into a bank with something that resembles an explosive device around his neck. He demands that money should be transferred to a predetermined account. If not, he will blow himself and the bank up.
The man, who is known as Planet-Göran and claims that his father’s name is Sitting Bull, is regarded as the village idiot. Planet-Göran is considered to be completely harmless and is, at first, not taken seriously. However, soon everyone realizes that the explosive device is real – the village idiot’s threat is serious.
