Plot
Mike is a homeless young man in London, struggling with addiction and poverty. One morning, he accepts money from an older couple, but then notices a mysterious older woman playing violin and staring at him. He later discovers his wallet is missing and accuses Nathan of stealing it. They fight outside a café until a man, Simon, intervenes. Mike recovers his wallet but apologises to Simon, who offers to help him by getting him a sandwich.
However, as they walk, Mike suddenly knocks Simon unconscious, steals his watch, and rushes to a pawn shop to sell it. Outside, he is arrested, confronted with CCTV evidence, and remanded to prison. He calls his mother—who gives a cold response—and is processed into custody.
Upon release, Mike is warned by the prison officer not to return. He meets Nadia, who supports his reintegration, and is placed in a hostel temporarily. He reveals to her that he is adopted and has no meaningful family support. One night, Mike hears odd breathing and sees the violin woman again, then later showers as the camera follows a surreal drain-pipe into a dark, cavernous space.
Mike finds clothes at a charity shop for a chef job interview but flees when Nathan appears. During the interview, he confesses his criminal record. The restaurant owner, Franco, hires him for a trial shift. Mike integrates into the kitchen staff and continues meeting with Nadia, where he learns that a mediated meeting with Simon is forthcoming.
At work, Mike is asked to handle a food complaint by a customer—something he resists but ultimately does. Frustrated, he storms off into the kitchen storeroom, eventually cutting into another dream‑like vision of the cave. During his mediated meeting, Simon shares the distress the incident caused his daughter and family, which visibly unsettles Mike.
Back at work, Mike’s performance declines; food is returned and he clashes with a coworker. Franco fires him, citing unreliability. Mike reverts to his former job as a refuse collector. He is paired with Andrea, with whom he bonds. They sleep together and later attend a dance show, where Mike has flashbacks that reveal he beat Simon repeatedly after knocking him out. Horrified by his own actions, he flees.
Mike’s insecurity escalates: his hostel stay ends, he returns to the streets, and tries reconnecting with Nathan. He finds Nathan sober and living with Mary. Mike borrows some money but attempts to take more; Nathan reclaims the excess, and Mary returns, calm but distant. Mike spirals further, becoming intoxicated and confrontational in a nightclub. A bouncer throws Mike into a wall, and while trying to steal liquor inside of a shop, he passes out.
Later, Mike returns to where he kept his shelter months ago. After ingesting drugs, Mike sees the violin player walk out from a dark space behind him. He follows behind her and enters a large stone hallway. He is pulled down to the ground and toward a chapel room, which he enters on his own. Inside, the violin player is preparing something. Mike wanders into another room, where Nathan is seated in a robe in front of an alter with a head sculpt on it. The pair hug, and Nathan leads Mike to a door. Nathan abruptly opens the door and throws Mike through it, sending him tumbling through a void. Eventually, Mike seems content, and curls into the fetal position as he disappears into darkness.
