1944. Four powerful Fascist leaders in Mussolini’s Italy agree to marry each other’s daughters in a ritual of debauchery. With the help of several collaborators, four powerful Fascist leaders in Mussolini’s Italy kidnap eighteen young people (nine men and nine women) and lock them up in a palace near Marzabotto, where the Nazis carried out a massacre during World War II. In the great mansion, the law of the lords rules, and no one is allowed to escape. This law empowers them to dispose of the lives of their prisoners at any time and in any way, while transgressions are punishable by death.
