Leviticus

Following his father's death, Naim and his mother Arlene relocate to an isolated town in regional Victoria, Australia. While she finds comfort in the town’s deeply religious community, Naim struggles to accept its extreme beliefs and practices. His only refuge is Ryan, a local teenager with whom he begins a secret romance in an abandoned warehouse. Their relationship fractures when Naim witnesses Ryan kissing the pastor’s son, Hunter. Spurred by hurt, jealousy and fear of his own feelings, Naim impulsively outs Ryan and Hunter to Hunter's parents.

A self proclaimed “deliverance healer” is called on to perform a ritual intended to purge the boys of their homosexual desire and "sin." Wracked with guilt, Naim is unable to watch as Ryan and Hunter scream, vomit, and convulse in agony throughout the ritual. Afterwards, Ryan becomes withdrawn and the target of increasing bullying. Desperate to make amends, Naim attempts to check on him but Ryan pushes him away. Concerned for Ryan, Naim follows him and witnesses him talking to empty air ultimately leading ending up outside the local roller skating rink's photo booth. The photo booth prints out pictures of Ryan seeming making out with thin air before banging sounds come from inside the booth. Naim opens the curtain to see Ryan pinned against one of the corners and strangled by an unseen force. An injured Ryan runs from the booth, and when Naim asks him what happened, Ryan yells that it was him, and warns him to stay away.

Hurt and confused, Naim seeks out Hunter for answers and witnesses him being attacked by a similar invisible entity. Hunter's decapitated head is later discovered in a nearby field. Terrified that Ryan will suffer the same fate, Naim confesses to the police that he and Ryan were romantically involved and pleads with them to stop the entity. The police dismiss his claims and instead inform Arlene about his relationship with Ryan.

Claiming she wants to protect her son from hatred and persecution, Arlene arranges for the deliverance healer to forcibly perform the ritual on him. After the ritual, Naim confronts Ryan outside Hunter's funeral. The two kiss before Ryan begins attacking Naim. Naim runs back inside the funeral and sees Ryan there, realizing whoever he was with outside was not the real Ryan. Hunter’s sister, Izzie, reveals to them that a girl in a nearby town was recently killed under similar circumstances after the deliverance healer performed the same ritual on her and her girlfriend.

Determined to understand what is happening, Naim and Ryan track down the surviving girlfriend to Murrayville Hospital. She explains that the entity takes the form of the person its victim desires most. It only appears when someone is alone, and grows stronger over time. Worse still, there is no way to stop it. On the trip back home, the two make out in the back of the bus. To protect themselves from each other, Naim tells Ryan he plans to leave for the city and begs him not to follow. Ryan begrudgingly agrees before confessing that the entity will always follow them and if he has to live with it forever, he doesn't want it to be anyone else but Naim.

At school, Ryan is attacked by the entity which mutilates his ear in the bathroom. Meanwhile, Izzie consumed by grief blames the boys for Hunter’s death. Under the pretense of helping Ryan and Naim, she lures them to an abandoned car park, where she reveals that Naim was the one who outed Hunter and Ryan. A violent confrontation follows. Ryan fights off the attackers and helps Naim escape before telling him he never wants to see him again.

Petrified of being alone, Naim sleeps in his mother's room and the next morning, despite his desperate pleas, she leaves him home alone. That night, the entity attacks once more. Standing at Naim's screen door, despite knowing the entity is not really Ryan, Naim apologizes for outing Ryan before the entity breaks through the screen door and attacks Naim. Fighting back against the entity, Naim holds up a lighter and manages to escape to a nearby store, begging someone to stay with him after closing time. Eventually abandoned, he is chased by the entity to the derelict warehouse. Having learned that the entity is sensitive to fire, Naim sets the mill ablaze with the entity trapped inside.

Afterwards, Ryan's disappearance haunts Naim with the possibility he killed the real Ryan. However, authorities later confirm no trace of Ryan was found in the ruins. Arlene reveals to him that she knew the consequences of the ritual but believes fear is necessary to keep him safe. Betrayed, Naim abandons her at a gas station and flees to the bus stop to get out of town. He finds Ryan there, who appears exhausted, battered, and clearly with the same plan. Surrounded by other passengers, they are relieved to know that it is really them. Together, they board the bus and leave the town behind. As the bus drives away, Naim notices the entity lurking outside, but chooses to ignore it.
