Zetterstrøm (Ulrich Thomsen) once had a love affair with a woman (Helena Christensen), then left her and forgot all about his past, in favour of his musical career. While he is away from Copenhagen, a supernatural incident occurs, making the central part of Copenhagen inaccessible, over time it becomes impossible to enter the area due to some invisible shield. When Zetterstrøm returns to Copenhagen, he is oblivious to this incident and is guided by a mysterious man (Henning Moritzen) into the zone. Inside the zone, Zetterstrøm must re-experience his unresolved and traumatic love affair.
