Millionaire currency trader Lewis and his wealthy best friend Helen swap their lives of luxury with cleaner Nicole, joiner Grant and their three sons. Lewis lives in a sprawling country house near King's Lynn, Norfolk, complete with six deluxe bedrooms, while Nicole and Grant's Grantham three-bedroom council house has cramped bedrooms, threadbare carpets and a kitchen barely big enough for family meals. When the two families finally come together at the end of the week, emotions run high, revealing just how life-changing this swap has been.
