Stacey and her gang, organiser Dilly, carpenter Rob and cleaner Iwan, challenge the Edgar-Whelan family to sort their life out in seven days, and in order to do this, they will have to embark on a mammoth declutter. They ask the family to try and let go of half their possessions so that they can then beautifully reorganise their home.With Stacey's help, the family start packing all their possessions into boxes. Every single item is stripped from the family home, revealing how much space there is under all their things. We get to know the family behind the clutter – single mum Claire, who looks after five young boys between the ages of 13 and 24, with four of them still living at their family home but hardly contributing to Claire's endless chores.With the house all packed up, the family's possessions are laid out in a giant warehouse like an art installation of their entire lives, including 95 bottles of cleaning products, ten versions of the same board game, 234 pairs of shoes and over 300 pieces of kids' artwork. With everything displayed in front of them, the family are shocked to see how much they really own and how it all fitted into their house in the first place.There will be emotional moments as the family go through their most treasured items. In the warehouse, Claire struggles with self-confidence and finds it hard to let go of her belongings. After some gentle persuasion in the memory section, Claire only holds on to the best of her memories. The boys realise not contributing and leaving rubbish around the house doesn't help mum, and they promise to change their ways. The items they do decide to let go of will be put into piles to recycle, donate or sell.
