Killian Maddox is a mentally ill grocery store worker obsessed with bodybuilding. He lives with his grandfather ("Paw-Paw") as a result of his father committing
murder–suicide of himself and Killian's mother. His dream to be the best in bodybuilding aids in creating negative behaviors, with the
steroids he takes to support his physique, leading to physical ailments. Killian has frequent, recurring, emotional outbursts and appears unable to express his true emotions. His frustration sexually manifests through watching pornographic videos, but not masturbating. As he prepares for a show, he attempts to ask out his love interest, Jessie, at the grocery store where he works. He asks her out while he's shopping, only to walk out awkwardly. Killian talks about his bodybuilding goals and admiration for fitness champion, Brad Vanderhorn, in written letters. Killian also includes his phone number, hoping Brad would call. Killian threatens a local painter's shop as the owner refuses to repaint his grandfather's house due to his 'Paw-Paw's' claims of thin paint needing another coat; eventually destroying the shop's windows and inventory in a fit of anger. Killian attempts to flee the scene, but crashes his car and is knocked out. In the hospital after the accident, Killian is informed by a doctor that he has tumors on his Liver and that they require surgical removal immediately. Killian vehemently refuses the surgery, telling the doctor "bodybuilder's can't have scars". Killian takes Jessie out to dinner, where he
'dumps' about the deaths of his parents before devolving into an intense monologue expressing his bodybuilding dreams. Jessie leaves him at the restaurant. He's distraught as he focuses on his next fitness show. Immediately before the next show, the local painter owner's nephew and friends assault him, breaking his arm in the process and leaving him bloody and disfigured. Despite the beating, he drives to the show. He steps on stage and begins to pose in an injured condition, only to pass out. Killian watches a viral internet video of his embarrassing presentation on stage and, in a fit of anger, destroys his tape-collection of bodybuilding videos and bodybuilding posters in his room. Following the disaster of a show, Killian hides his true dark and violent feelings and real-life happenings from his counselor (informing his counselor that he's had his picture taken for a magazine and that his relationship with Jessie has actually worked out), eventually picking up Pink Coat with the intent to have sex, only to be unable to continue after she demands no kissing. Killian's spiral continues: he is fired from his job, he encounters the owner's nephew again, with his family, in a diner, causing a threatening scene. The police are called on Killian at the restaurant, and outside he damages a woman's vehicle before he is pepper sprayed by responding officers and arrested. Killian then begins purchasing and assembling guns. One day, Brad responds to Killian's messages and invites him to his next photo shoot. Upon their first interaction, Brad obliges Killian to feel his abs, and the pair spends the night together in a sequence marked with ambiguity regarding consent. Brad ignores Killian for a call from his wife, and Killian leaves wordlessly. Killian, in the wake of this, continues fantasizing about murder. He breaks into the home of a judge who provided a criticism that he returns to several times over at earlier points in the film, forcing him (at gunpoint) to strip and pose. Killian then attends Brad's posing show armed with a gun and has a vivid fantasy about shooting and killing Brad on stage during a disorienting montage sequence featuring previous moments from Killian's life, including interactions with his parents as a child; though Killian ultimately leaves without shooting. Upon returning home, he breaks down in his Paw-Paw's arms, disassembles his gun, throws it away near a set of train tracks, dumps his steroids into a toilet, and commences flexing, yet again, in his garage, reiterating his still-existing bodybuilding dreams in voiceover narration. ==Cast==
