A Serbian Film is about a semi-retired porn star, Milos, with a beautiful wife and young son who is financially strapped and looking to earn enough money to solve his financial problems in Serbia. He is lured back by his former adult film co-star, Layla, and a supposedly visionary director, Vukmir, who promises a great deal of money to make an art house porno film. The director is interested in Milos' ability to get and maintain an erection without any visual or physical stimuli. Reluctant but financially desperate, Milos takes the job without knowing much about it other than it is supposed to be more realistic and that Vukmir appears to be well-connected and wealthy.[3][4]

Milos is picked up the next morning and dragged to a warehouse where he is supplied an earpiece, from the local sheriff. A voice speaks to him from the earpiece, telling him each move, and he follows.[3] The film crew follows him around with cameras and puts him in situations to see how he will react.[5] Initially, it seems fairly straightforward; however, a little girl appears and things begin to get more violent than he finds comfortable.[3]

Vukmir shows Milos a clip of a man helping a woman give birth to a baby girl; the man then proceeds to rape the newborn in what the director calls "newborn porn".[6] Milos quits and storms out to his car. He is approached by an attractive woman and he cannot take his hands off of her. Milos suddenly wakes up in his bed, bloodied and beaten and with no memory of what has happened or how long it has been. He returns to the set and finds a number of tapes. He learns that he was drugged, made to rape, beat and brutally murder a woman. Driven over the edge, he wants revenge on Vukmir.[5] However, during this time he sees videos that reveal a masked man choking a nude woman who has had her teeth pulled out, revealed to be his friend Lejla, and, during sex with a woman handcuffed to a bed, her head is sliced off to induce rigor mortis during sex.[7][6] Milos is drugged again, taken into a room and has sex with a body hidden under covers. A masked man enters and begins to have sex with another body beside the one Milos is raping. The masked man is revealed to be Milos' brother who was jealous of Milos and wanted his wife for his own and the body he is raping is her. The covers are taken off of the body Milos is raping and it is Milos' young son, drugged and in a state of shock. Milos gets hold of a gun and shoots Vukmir's bodyguards dead. Confronted with one of the bodyguards, Milos attacks him and knocks off his sunglasses; the guard is missing an eye so Milos rapes the eye socket.[6]. Milos' brother's head is caved and smashed to pieces by his wife who has since recovered from the drugging. Vukmir is also killed in the melee. Milos tries to kill himself but there are no bullets left. Milos returns home after punching his wife unconcious and he, his wife and his son hold each other in bed. We see that Milos is holding a gun behind his wife's back. He pulls the trigger killing all three. A businessman enters with bodyguards and a camera crew. He says start with the little one, and an actor unzips himself.
