Since Osvaldo is a wealthy landowner, his beautiful wife Maria is forced to live in the countryside. But some wild party with neighbors is certainly not enough to alleviate her dissatisfaction. She has long lover, Alessio, a depleted man and hardened player. At one of the parties in question, the banker Tesser intervenes, who has every intention of taking Osvaldo's vast property possession, as well as Claudia, an elegant woman whom Osvaldo has fortuitously met in the woods and rescued during a fall from a horse- in fact she is Alessio's wife. But the presence of Claudia at the villa is not occasional: it is Tesser who is in agreement with Alessio, so that in a gambling night Maria, an avid gambler, is played by them. Maria loses a large sum of money to Alessio and he makes her sign a paper for this debt. Alessio gives this paper to the banker Tesser against some money. Meanwhile Osvaldo and Claudia fall in love (and then meet in the inn of the nearby village). After a quarrel Alessio, since he obtained what most urged, wants to get rid of Maria, she holds a revolver: a blow starts, but she dies, while the lover flees. In the villa Osvaldo and Claudia are now free to live united.
