It is 1972: a group of teenagers from Dublin and Derry are spending a month in Donegal, learning Irish language and culture. Liberated for the first time from the restricting reins of parental control, they respond to the untamed landscape of river, hill and sea, finding in it unnerving echoes of their own submerged - and now emerging - wildnesses. Eilis Ni Dhuibhne uses the experiences and emotions of girls on the cusp of womanhood to explore dangerous territories of sex, politics, class and Irishness.
