Tenancy enforcement manager Alan Kibble has a tenant whose chaotic lifestyle is ruining the family life of Kerry, Greg and their three children. Sleepless nights and stress from late-night rows, loud music and swearing from their next-door neighbours have driven them to despair, and they have turned to their housing association for help. Alan's team decide to gather evidence with CCTV and noise monitoring equipment. Scott has been sleeping in the lounge of his housing association home for seven years, after a degenerative back condition stopped him using the stairs. Scott and his partner, Joanne, have tried to manage and have avoided asking for help. But life has become so tough that they have turned to their local housing officer, Jen Bradley, for help to get a bigger home. Meanwhile, housing manager Sean Ellam is called to a flat where drug addicts have turned a home into a hell-hole. The flat is scattered with needles, and it has been stripped of everything of value - even the kitchen sink. The tenant is nowhere to be found, and Sean needs to find out if he is safe - but also if he is responsible.
