Created and written by Lisa McGee, the show follows a group of Northern Irish teens and their families in 1990s Derry, who always find ways to amuse themselves and get on with their lives despite a divided political atmosphere. In series three, there’s hope in the air that The Troubles may finally be over, but the group’s troubles are only just getting started as they get ever closer to adulthood.
