Colm Tóibín tells the story of Easter 1916, following the main personalities involved, in particular Thomas Clarke and Patrick Pearse.

Yeats and James Joyce challenged the popular myths surrounding the uprising, and considers the "stark divergence in the after-image" as it appeared in England and Ireland.
