Joe fights him and eventually knocks him out also, then picks up the pitchfork and kills the unconscious older man.

Liliana, her sister Paola, and her husband Sergio arrive, set up, and have dinner.

The next morning, Sergio goes off to hunt with a shotgun, Liliana goes into town to do the shopping, and Paola sets out a chair to sunbathe.

Joe forces Paola and Sergio to have sex by aiming a shotgun at them, then tries to seduce Liliana.

Madness was based on a story by Mario Gariazzo, who director Fernando di Leo had previously offered script advice for his film The Bloody Hands of the Law and whose films were produced by di Leo's company Cineproduzioni Daunia 70.

"[1] The director stated he was a hired hand on the film, which lead him to feel that "you don't always have the chance to do what you want, and often you know very well you're making a bad movie, but you do it anyways.

[1] The film is currently available to stream on Kanopy (as of July 2020) and an edited version on Amazon.

The unedited version is available from Raro Video on DVD (2012), which is also distributed by Kino Lorber.
