In the claustrophobic confines of a rural estate, a family struggles with their tangled web of hereditary diseases. Among them is Alessandro, a young man with epilepsy and paranoid tendencies. Feeling burdened by the numerous afflictions that plague his family, he decides to relieve his only healthy brother, Augusto, from the weight of their shared responsibilities. However, Alessandro's obsessive project takes a dark turn when a series of dreadful accidents and murders is set into motion. The chilling sequence begins with the intentional act of pushing their blind, religious mother into a ravine. This sinister act is followed by the elimination of Leone, the intellectually disabled brother. Throughout this macabre scheme, Alessandro grapples with his own desires, including an unsettling inclination towards incestuous impulses with his sister, Giulia. Meanwhile, Giulia clumsily attempts to thwart Augusto's plans of leaving the family by sabotaging his relationship with Lucia, whom he loves deeply. As the family dynamics intensify, the question arises: Will Alessandro be able to bring his obsessive project to completion? Will he succeed in freeing himself and Augusto from their mother's demands and familial obligations, allowing them to pursue a new life together in the city? Or will unforeseen obstacles stand in the way, challenging Alessandro's twisted ambitions and disturbing plans?
