Stacey and her gang, organiser Dilly, carpenter Rob and cleaner Iwan, challenge the Bufton family to sort their life out in seven days. To do this, they'll 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 just how much space there is under all their belongings.

We get to know the family behind the clutter – single dad Craig has been bringing up his young daughters, six-year-old Merywen and four-year-old Wren, after their mum, Lois, passed away from cancer four years ago. Supported by Lois's close family, dad Craig feels now is the right time to tackle the clutter in their home and make a positive change for his daughters.

Packing up the house is an emotional process, and with the house now empty, all the family's possessions are taken to a giant warehouse and beautifully displayed like an art installation of their lives. There are thousands of belongings, including 197 teddies and dolls, 121 old socks, 373 pieces of unopened mail and 1,239 books.

Stacey and Dilly are on hand to guide the family through the sort-out. There will be emotional moments as the family go through their most treasured items. Mother-in law Soo and sister-in-law Cass are on hand to help Craig make decisions, and we learn about a beautiful children's book Lois had written for her daughters. As part of the process, Craig confesses he's been taking up hobbies and buying random stuff online to fill the void left by the loss of his wife.

Stacey and her gang – organiser Dilly, carpenter Rob and cleaner Iwan – challenge the Mistry family to sort their life out in seven days. To achieve this, they'll 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 – parents Nila and Nat, and their grown-up children, son Jai (26) and daughter Roshni (30). With multigenerational living causing arguments due to the mess, it's time for the family to sort through the clutter that has taken over the house.

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 361 glasses, 76 jars of spices and over 5,000 bangles.

With everything displayed in front of them, the family are shocked to see how much they really own, and wonder how it all fitted into their house in the first place.

There are emotional moments as the family go through their most treasured items. We learn that Nila arrived in the UK in the 1970s as a refugee, with her family's only possessions wrapped in a sheet, so she struggles to let go of items they worked so hard to acquire in the first place. And both Nat and Nila put almost every penny they have earned into expanding their two-bedroom house, welcoming in elderly parents in poor health so they could look after them and continuing to provide a space for son Jai, who can't afford a place of his own.
