In Victor’s beautiful villa, Nadine, a beautiful girl appears to do a photo shoot, taking up seductive models covered only with a little underwear. After shooting the girls leave early, but Nadine remains: the landlord has challenged her to play chess and the mail of the match will be the same as Nadine, for Victor if he loses, there will be suicide. His wife, Luciana accepts the strange idea, because she loves him, who was also the lover of Valeria, the secretary. While Nadine plays with alternate luck – and this for three days – she relives past moments: not only the violence once suffered on the train during a trip, but also the intense passion for her husband.
