Long after the death of Brodies' father, his mother is institutionalized at a mental hospital. The teenager is thus obliged to move into his uncle's place in Greypoint. Brodie is a heavy metal fan, which conflicts with Uncle Albert's orthodox Christian beliefs. His fellow high school students regard him as an outcast, which leads to bullying from other boys (including his cousin, David). Brodie's only friends are two "losers" named Dion and Giles, both of whom spend most of their time playing role playing games. However, he soon becomes acquainted with another heavy metal fan named Zakk at a local record store. Shortly after, Zack, Brodie, Dion, and Giles form a metal band called 'Deathgasm'. To Brodies' surprise, the beautiful Medina appears to be interested in him and invites him to have ice cream with him. However, Brodie is too shy and misses the chance to kiss Medina by the end of the date. Later, Zakk tells Brodie about the metal musician Rikki Daggers who is allegedly living nearby. He convinces Brodie to accompany him in a burglary into an abandoned house where he suspects Daggers to be hiding. In fact, they find Daggers sleeping in the house and try to steal a record which he is holding in his hands. Anyhow, Daggers wakes up and attacks them, but as he hears another noise in his house, he hands them the record and tells them to run away. Moments after Zakk and Brodie have left, a well-dressed man enters the house and kills Daggers. He appears to be part of a worship which is looking for medieval sheets of music because those are supposed to have occult powers. Since the killer failed to obtain the sheets of music, the cult's leader later gets him beheaded. At home, Brodie notices the sheets of music which were hidden inside of the record's cover. The band tries to play them which already causes strange happenings: Brodie's uncle Albert hyperventilates and starts to bleed slightly from his eyes, but the band does not notice this. It is only Brodie who feels that something is going on which is why he abruptly stops to play his guitar before they manage to complete the hymn. As Zakk asks him why he did so, Brodie tells him he does not feel well. The next day in school, Brodie translates the Latin writing on the old sheets of music. He finds out it reads: "The black hymn. Play it to invoke the deamon.". On the way home, Brodies cousin David lies in wait for him and beats him up violently to make him stay away from Medina in which he is also interested. In the meanwhile, Medina meets Zakk by chance. She tells him that she could not find Brodie and asks him to give him a note. Zakk reads the note and finds out Medina wants to meet Brodie at the local park in the late evening. He does not pass it on to Brodie, but goes there himself and lies to Medina that Brodie does not want to see her. Then, he puts his jacket around her shoulders and they engage in kissing. Brodie has the suspicion that playing the hymn on the sheets of notes is somehow connected to dark forces. Due to the humiliation by David and his friend, he wants to take possession of these powers to take revenge and therefore calls the band together to play the hymn. After having played it, the stereo equipment explodes and all band members fall unconscious. After waking up, all four notice that something has changed. Firstly, Brodie meets a strange and frightening being in the school's toilet which threatens him. Secondly, one of the teachers starts to bleed from his body's orifices and throws up blood on a student during a lesson. In the evening, Brodie meets Zack in a repair shop to tell him what happened where they are attacked by Zakk's father. The latter acts like a zombie, tears out his own eyes and then tries to kill them, but the two manage to defend themselves and kill him. Meanwhile, Dion and Giles too are attacked and nearly killed by a zombie, but Medina manages to save them by killing it using an axe. They decide to hide in the school's panic room and leave a note on Brodie's door to inform him about their whereabouts. Trying to find out what is happening, Zakk and Brodies meets with a fortune teller. She tells them they have invoked the deamon Aeloth "The Blind One" by playing the hymn and that the residents of town are transforming into zombies which kill every human being in order to prepare Aeloth's arrival. By 3 AM, Aeloth will merge with the most evil human being present. Before she is able to tell them how to undo Aeloth's summoning, she is killed by two zombies. Zakk is not interested in fighting Aeloth any further and decides to watch the town's doom from a nearby hill, but Brodie manages to convince him to help because he assumes the summoning will be undone by playing the black hymn backwards. They drive to Brodies house to obtain the sheets of music. However, Zakk secretly removes the note stuck to the door by Dion, Giles and Medina and the sheets of music are blown out of the window by the wind. Suddenly, they are attacked by Brodie's uncle Albert and his wife Mary who have transformed into zombies, but manage to kill them using three dildos and a chain saw. In contrast to his parents, Brodie's cousin David has not transformed yet, but anyways Brodie sews his head off in revenge using the chain saw as he enters the room and asks what is going on. Having decided they will search the sheets of paper, Zakk and Brodie craft a few weapons and go after them. In the meantime, the members of the cult have come to Greypoint to serve Aeloth. They meet the strange and frightening being which Brodie had met in the school's bathroom. It appears to be Aeloth's ambassador who promises the cult's leader that Aeloth will merge with him. In this moment, the leader is killed by his own mistress who then claims the lead of the cult. After having found all the sheets of notes, Zakk and Brodie go to the school building since they know there are amplifiers which allow them to play the hymn backwards. There, they meet Dion, Giles and Medina. As Brodie notices Zakks jacket in Medina's bag, Zakk's lie is revealed. Zakk tells Jack he is not interested in Medina but simply wanted to have some fun to which Brodie responds with a punch to Zakks face. A fight ensures between the two which Zakk manages to win. He then decides to leave town. Moments later, the remaining four are taken into custody by the members of the cult and brought into the house of Rikki Daggers in order to serve as sacrifice for Aeloth. However, Zakk feels remorse for his friends and returns to his friends. He manages to free them and they attack the cult during their ritual for Aeloth. Brodie starts to play the black hymn backwards while the others defend him from the attacks by the cult members. In this fight, most of the cult members as well as Dion and Giles are killed. Brodie does not manage to play the hymn entirely before 3 AM, so Aeloth is able to enter the cult leader's body. Zakk then kills her, but since he is the most evil person amongst the remaining, Aeloth then takes possession of his body. It is only now that Brodie manages to complete the hymn which weakens the deamon. Zakk collapses and transforms back into his human body, but since Aeloth has already entered the dimension, he is about to retake possession of Zakk. Hence, Zakk urges Brodie to kill him in order to prevent the deamon's resurrection which Brodie eventually does. A few months later, Brodie and Medina are a happy Death Metal couple in Greypoint. The scene ends with a friendly message by Zakk to Brodie which the latter hears through his record player. It seems Zakk is still melded with Aeloth in a parallel dimension.
