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.

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.
