These are the terrifying tales of the unwanted neighbors who turn home sweet home into home sweet hell. A look inside the lives of horrific neighborly disputes and what happens when a simple issue turns into the worst night of a family's life. Do you really know who lives next door? This true-crime series tells the chilling tales of those with the misfortune to unwittingly take up residence within a stone’s throw of a psycho or killer.

Mr. Belvedere takes a job as a housekeeper with an American family headed by George Owens.

Neighbours on an idyllic suburban street have a falling-out over one family's plan to build an extension to their house.

Different presenters and their teams tackled a neighborhood dispute in each episode with the intention of resolving it. Presenters John Williams and Natasja Froger, then Jochem van Gelder and Patty Brard & later Dennis van der Geest and Leontine Borsato each individually committed themselves to one of the two parties. They listened to the story from both sides and then proposed a solution.

Neighborly fights usually begin over small things. A fence that overlaps a property, a dog that barks endlessly, a lawnmower starting up every Saturday at 7am, animal excrement in a garden, a terrace which is too high. Jealousy, envy, family disputes, racism, and you have a recipe for neighbors to be swept into an escalation of incomprehension, arguments, and lawsuits. A territorial war is declared and both parties feel invaded by the enemy, the neighbor.
