The girls have been up all night cramming for a big exam. Some (Michelle and Erin) haven't studied for it enough whilst Clare's over-studied, leaving herself completely sleep deprived and slightly manic. Everyone is convinced they're going to fail. So when a distinctly dubious opportunity presents itself to get out of the exam they jump at the chance. Especially as it involves them spending time with the very beautiful Father Peter.
Return of the comedy set against the Troubles in 1990s Northern Ireland. Erin and the rest of the gang are excited to attend an outdoor pursuits weekend which aims to bring Protestant and Catholic school kids together as part of a peace initiative.
Erin lives with her father Gerry and mother Mary, her baby sister Anna, Mary's younger sister Sarah, Sarah's daughter Orla, and her maternal grandfather, Joe. James is Michelle's cousin; his mother Cathy left Derry for England to have an abortion but gave birth to him and raised him in London. She sends him back to Derry to live with Michelle and her mother Deirdre when she is going through a divorce.
