William Brown, an anxious and self-obsessed musician, is single-minded in his pursuit to complete his magnum opus—a grand, intricate prog-rock album. However, his creative progress is constantly thwarted by a noisy, grotesque neighbor named Vlad, whose loud and unruly behavior drives William to the brink of madness. After enduring weeks of frustration, William finally gathers the courage to confront Vlad and demand some peace and quiet. But things quickly spiral out of control when, in a moment of panic, William accidentally decapitates Vlad during the confrontation.
Instead of resolving his problem, the murder sets off a series of increasingly bizarre and violent events. Desperate to cover up his crime, William finds himself in a downward spiral as his attempts to hide Vlad’s body only lead to more chaos. As the bodies pile up, something even stranger happens—each new victim rises from the dead, transformed into vengeful, undead creatures that haunt William’s every move. These relentless revenants not only torment him but also complicate his already fraught efforts to finish his masterpiece.
Caught between his obsession with completing his prog-rock album and the escalating horror of his unintended killing spree, William becomes entangled in a nightmarish cycle of violence, guilt, and madness. As the undead corpses continue to multiply, they wreak havoc on his once serene life, forcing him into increasingly absurd and bloody detours in his pursuit of musical perfection. What started as a simple act of self-preservation soon escalates into an uncontrollable chain of events that threatens both his artistic ambitions and his sanity.
Now, with a growing army of undead enemies, William must navigate his own unraveling mind, all while trying to finish his opus and avoid the ever-looming consequences of his murderous actions. With each horrific encounter, the line between his musical dreams and nightmarish reality becomes blurrier, as he races against time to achieve the prog-rock Valhalla he’s always envisioned—if he can survive long enough to finish it.
