Londonderry in the early 1990s. A trying day for 16-year old Erin Quinn begins when she wakes to find cousin Orla reading her diary. Starting a new school term with Orla, saucy Michelle and socially-conscious Clare she sees the desirable David Donnelly and meets nervous English lad James, the only boy in the school. After a set-to with smug Wee Tina the girls and James are put in detention which is agony for James, who is banned from using the girls' toilet and relieves himself in a waste bin. When the ancient nun, Sister Declan, supervising them dies they find themselves accused of killing her and to top off a lousy day James mammy has gone back to England and Orla starts reading Erin's diary aloud.
