At long last there is an air of calmness about Brat Camp as it comes to its inevitable emotional conclusion for most - if not all - the girls-only group.

After seven weeks in the Utah wilderness, the seven girls have hiked, fought and struggled to face their demons and graduation is at last on the cards.

Sugar and spice and all things nice are just not what these girls are made of...

Posh spoilt brat Poppy, 15, has had her own way since she was born. Struggling with depression, Rosie, 15, simply refuses to go to school. Middle-class tearaway Georgie, 16, has an arrest history as long as her arm. Lazy stoner Julia, 16, smokes 20 spliffs a day. Complete drop out Lydia, 16, left school with no qualifications. Runaway Danni, 15, has left home more than 70 times in one year. And Lucy, 15, terrorises her family with her violent rages.

But weeks in isolation without drink, drugs and cigarettes have had an affect.

One girl in particular, 16-year-old Lydia, has managed to keep her head down all the way, and feels sure she'll be first on the plane home. But nobody is going anywhere until staff are convinced the girls are ready, and they have a few surprises up their sleeves.

The group of seven have turned into a group of six, and it's down to three as the parents of the first three graduates make the journey to Utah. For others there is more waiting and hoping as the second graduation gradually looms, but will Lucy, the worst-behaved brat of all, ever be allowed to leave Utah?

Tonight's final episode features the families' emotional reunions and reports on the girls' progress once they are back at home. Cameras catch up with the girls and their families in their 'natural environment' and the crucial question is asked: has Brat Camp changed their lives for the better?
