Big changes are coming to late-Sixties Belfast. At first life seems normal for Sammy and Maeve, two children from the opposing republican and loyalist communities. Sammy tries to avoid trouble with his unemployed father, while Maeve has lived with her aunt and uncle since her mother’s death. When twins Dylan and Emma Goldman move from Washington to Belfast they strike up friendships with Maeve and Sammy.

Gradually the nationalist girl and loyalist boy overcome their suspicions of each other, and all four children become friends. But even as they have fun at local sports clubs, attend the Goldman’s barbeques, and secretly make their own radio programmes, they can’t ignore the trouble that is slowing gripping the country. And when the simmering tensions in Northern Ireland erupt into violence it threatens not just their friendships – but their very lives.
