Wallander (2005)

S1E2 The Village Idiot

A man storms into the bank with what looks like a bomb strapped to his neck, threatening to detonate it unless money is wired to a specific account. Known in the community as the village idiot, he bizarrely insists that Sitting Bull is his father. Initially dismissed as a joke, the situation turns serious when they discover the bomb is genuine. This raises questions about whether the village idiot is acting alone or if others are implicated. Kurt Wallander and his team embark on a lengthy and intricate investigation to uncover the truth.
