It's the first summer of lust for 14-year-old Jim Finnegan, a boy trying to become a man in 1980s Dublin. Jim watches his parents argue, his five older sisters fight, and the local network of mothers gossip. Over the summer, Jim wins the attention of a beautiful older girl-but he also becomes the unwilling target of a devious religious figure in the community. His life starts to unravel as he faces consequences from both his love for his girlfriend and his attempts to avoid the Parish Priest. When he and his girlfriend take a ferry for a clandestine trip to London, the dark and difficult repercussions from the trip force Jim to look for the solution to all his problems in some very unusual places.
