Stacey visits Thomas and Cathy, who have an open marriage and live a polyamorous life, sharing their home with Nicole, who is a part of their relationship.

Stacey spends a weekend with the Saccone Jolys, one of Britain's most popular YouTube families. They have four kids who have been in videos since they were born.

In Brighton, Stacey stays with Matt and Adele and their three children, 8 year old Ulysses, 4 year old Ostara and baby Kai. Adopting childled parenting, Matt and Adele believe that kids don't need rules – just freedom to choose how they live and learn. They co-sleep with their parents, do not attend mainstream school, decide what they eat and when they eat, have no fixed bedtime and the parents are against mainstream medication.

Stacey travels to Preston to spend time with a family who have encouraged their teenage son, Kyle, in his amateur career as an MMA cage fighter since the age of four. Kyle is now 14 and home schooled, so he can concentrate on his fighting. Stacey goes to watch Kyle in a big cage fighting competition - where he will be fighting in front of a large crowd - to see if he has what it takes to be a champion and Stacey questions whether it is right to put your child in the cage.

The Preston family from Ashton-under-Lyne are members of the Jesus Christ Church of the Latter-day Saints, or more commonly known as Mormons. Eldest son of three, Adam, is seventeen and deciding whether to become a missionary for two years. Stacey joins the family, and finds out what it’s like to grow up with the strict parenting code of the church - including no tea, coffee, alcohol, and strictly chaperoned dating.

Stacey visits a wealthy family in their manor house in the Warwickshire countryside, challenging their views on privilege, inherited wealth and private education.
