Tony Duran, a mysterious foreigner born in Puerto Rico and educated as an American in New Jersey, is murdered at the beginning of the 70s in a village in the province of Buenos Aires. Before dying, Tony had caught the eye of everyone around him: admired, observed, different, but also fascinating. He had arrived with the beautiful Belladona sisters, the twins Ada and Sofia, daughters of one of the most important families in the area. He had met them in Atlantic City, where they formed a happy menage a trois, until one of them, Sofia, perhaps the weakest and the most sensitive, escapes from their torrid game of casinos and flesh. But Tony Duran continues his affair with Ada, following her when she returns to Argentina, where he meets his end.
