Special episode featuring the most extreme nightmare neighbours.

Documentary focusing on disputes with murderous consequences. Russell moved to Cheltenham with his wife Leo, and soon formed a firm friendship with next-door friendship George. But when Russell erected a pergola, tempers flared over the garden fence, and a violent saw attack saw both men at loggerheads. A couple in Chelsea were unhappy when their neighbour submitted plans for a basement build, claiming the construction would destroy their peace and work - but that was nothing compared to the surprise they got after catching him on CCTV.

One-off special focusing on vulnerable people who live in fear, including an elderly pensioner who was knocked to the ground during a violent assault, a man whose peaceful retreat is ruined by some vicious dogs and an abusive owner, and there's a flasher in the midst in Frinton.
