Five modern young women place themselves in the hands of a Norfolk convent. Two of them have a fight at the top of a cathedral, a broken false nail is compared to world famine by another, and they all decide they need a night out. However, the nuns' calming, wise words appear to be having their effect and the girls are showing signs of paying attention.

The sisters set the girls their final and toughest mission yet, to go home for a week and put to work the lessons they have learned.
