In the shadowy corridors of a London tower block, Adam, a reclusive television screenwriter, finds himself enveloped in a world of isolation and despair. The only fleeting joy in his grim existence comes from his vibrant neighbor, Harry, who unexpectedly shows up on Adam’s doorstep one tumultuous night. Although Adam initially shuns him, preferring solitude, Harry’s presence ultimately serves as a catalyst for change, prompting Adam to face his lingering loneliness.

As the outside darkness mirrors his inner turmoil, Adam immerses himself in his writing, trying to escape his sorrow and yearning for the warmth of his childhood home. It is within these familiar walls that he confronts memories of his parents, whose tragic death in a car accident when he was merely twelve years old has left an indelible scar on his heart. A poignant visitation from beyond the grave allows him to reconnect briefly with them, filling the void of their absence with a touch of warmth and love.

However, this fleeting moment of solace is shattered when Harry reappears. As their relationship blossoms, Adam is drawn into the complexities of Harry’s own struggles with emotional distance and a fractured familial connection. Together, they embark on a profound journey of self-discovery, slowly constructing a life built on shared experiences and mutual understanding.

As Adam’s bond with Harry deepens, he continues to experience visions of his parents, where he bravely faces long-buried secrets and unsaid truths. He finds solace in his mother’s unconditional acceptance of his sexual identity, and a heartfelt exchange with his father allows him to release the burdens of silence surrounding his childhood bullying. However, just as Adam starts to heal, he succumbs to the temptations of self-destructive behavior, spiraling into a world of club nights fueled by ketamine. A sudden blackout leaves him feeling lost and disoriented, only to awaken amid his parents’ joyful Christmas celebration, surrounded by laughter and the warmth of their love.

Yet, this serene escape is transient, disrupted by the harsh light of reality. Adam wakes in his own bed, the pain of his parents’ loss still raw and heavy on his heart. He drifts off to sleep again, realizing that the scars of his past have not yet truly healed.

A jarring ride on the Underground serves as a stark reminder of life’s fragility as Adam encounters Harry once more, whose aloof demeanor foreshadows future troubles. A terrifying vision of his younger self screaming at his reflection in the train window becomes a foreboding symbol of the emotional upheaval that awaits him.

As Adam’s world crumbles, he relives the nightmarish events surrounding his parents’ death, with Harry’s attempts to comfort him only highlighting the chasm forming in their relationship. The journey toward healing seems perilous, demanding that Adam confront the shadows of his past and carve a new path illuminated by love and support.

When Adam invites Harry to meet his parents, the tension and unease between them escalate, fueled by Adam’s increasingly reckless behavior. Upon arriving at the deserted family home, Harry grows anxious, urging Adam to leave. But as they prepare to depart, Adam’s mother’s ghostly figure appears in the window, her gaze heavy with unspoken emotions. Adam’s frantic knocking shatters the pane, unleashing a flood of unexpressed feelings and desires.

Awakening beside his parents, they reassure him that Harry has gone home, allaying their fears for Adam’s mental health. They guide him to a beloved childhood spot, where he bravely recounts the details of their tragic demise. A blend of relief and sorrow washes over them as his mother learns that they died instantly—though this narrative turns out to be a comforting fabrication.

As tears are shed, the family’s bond transcends death, and they vanish, leaving Adam to grapple with the reality before him. He finds a sense of comfort in the thought of Harry waiting for him at home. Yet, upon arriving at Harry’s apartment, he is struck by a terrible smell, evidence of addiction’s devastating grip. In the midst of decay, he discovers Harry’s lifeless body clutching the very whiskey bottle that first brought them together.

Haunted by grief, Harry’s spectral form appears to Adam, embodying the mourning and despair that reflect Adam’s own emotional landscape. In a moment filled with sorrow and solace, Adam cradles Harry as they dissolve into a resplendent beam of light, enveloped by the vastness of the universe, symbolizing hope amid eternal darkness.
