Zee lives in a quiet suburb of Belfast, with an apparently idyllic family life. But Zee's father was shot dead in front of them all, and the whole family is still struggling with the extent of grief and pain that this has caused.
Her brother Gary has become a rabid anti-Catholic, and a fervent Orange-man. And Zee? She's trying desperately to continue a normal life. Unfortunately, as a teenager this means boyfriends, and she is irresistibly drawn to local boy Conor, who's from the token Catholic family in the street. Gary will kill him if he realises, and even the adults will use any means to separate them if they are discovered. As Zee and Conor keep up a double life, and argue over the need to do so in what is, after all, their own hometown, the jealousies and petty hatreds of those around them come to a head.
Conor is beaten up – but Zee pays for her 'disloyalty' tragically.
