The action of the film takes place in 1978, in a fictional town called Acqua Traverse in Southern Italy, during the hottest summer of the century and the infamous Years of Lead. A nine-year-old boy named Michele Amitrano and a group of his friends set out on a race across scorched wheat fields to a deserted farmhouse. Michele's sister tags along but falls over, breaking her glasses, and she calls out to Michele, who runs back to her. Michele quickly calms her worries about the glasses, and they continue running. They are the last of the group to arrive at the farmhouse, which means that she and Michele must pay a forfeit. However, the leader of the group, Skull, chooses the only girl in the group apart from Michele's sister to pay up instead. He instructs her to expose herself to the boys, and she looks to the others for help, but they refuse to meet her gaze. She reluctantly and hesitantly begins to take off her clothes, when Michele pipes up that he was the one to arrive last and he should be the one to pay.
