Director Max Marsh (Aldo Mayo) flies to Argentina to make a sexually explicit film with his girlfriend and star, Terri London (Mirtha Massa). Unbeknownst to Max, Terri has taken a new lover, a rich playboy named Horst (Clao Villanueva), who lives on his father's nearby estate. Terri becomes pregnant by Horst, threatening the production of the film, though the entire shoot is canceled when Max is murdered during a street carnival. Meanwhile, a woman named Angelica (Margarita Amuchástegui), who lives in the mansion with Horst, is in cahoots with a vicious band of female hippies who are in thrall to a Mansonesque leader named Satan (Enrique Larratelli). He preaches that the decadence of the rich must be punished, and plans to start with Horst's family. Angelica's mission was to become pregnant by Horst in order to provide a baby to be sacrificed as the first victim in Satan's war against the wealthy. However, the news that an American film star is carrying the child is even better, and the band of killers bide their time (though they keep busy by swimming naked and murdering innocent shopkeepers). Six months later, the girls return to Horst's estate, where a lascivious, drunken party is in full swing. The guests are murdered, Horst is castrated, and the pregnant Terri is stabbed to death in her bed. At this point in the film, the camera pulls back to reveal the set -- the director of Snuff is seen congratulating the actors for such great performances. He convinces one actress to join him on the bed, where they begin kissing. When she realizes that she's still being filmed, she gets confused, and the director suddenly brandishes a knife. With the help of two production assistants, he cuts off a finger, saws off her hand, and then disembowels her. He holds the entrails in the air and howls with triumph as the film suddenly runs out and members of the crew say, "Ok, we got it, let's get out of here!"
