A body is discovered at an ATM, initially thought to be the result of a heart attack. Meanwhile, two teenage girls are taken into custody for the savage killing of a cab driver, openly admitting to the act without showing any signs of guilt. Both cases appear straightforward at first. However, as Wallander investigates the motives behind the girls' actions, he uncovers a far more intricate web of deceit than he originally anticipated. The two seemingly unrelated incidents converge, revealing a conspiracy that extends well beyond Sweden's borders.
