In a school in small-town west of Ireland, Connell is a well-liked, good looking and athletic student. Marianne is a proud, intimidating and unpopular loner who actively avoids her classmates and questions her teachers’ authority.

The night of the Debs is approaching and the girls at school have organised a fundraising event. Marianne has been asked to help and is out of her comfort zone. At the club, one of Connell’s friends Karen does her best to show Marianne some kindness but Rachel behaves coldly towards her.

Months later, school has finished and Connell arrives at Trinity College, Dublin. He has found a room in a house-share and meets his new housemate Niall. Despite his efforts, he feels out of place and struggles to articulate himself when surrounded by his eloquent and wealthy peers.

Connell and Marianne are back together. Connell has gained confidence in college; giving presentations in class and getting good grades but is reluctant to show Marianne affection in front of her friends. Will the two be able to admit that they are together?

After a tragic event, Connell struggles with severe depression. Marianne remains a lifeline for him from abroad.

Marianne and Connell are back in Dublin and together as a couple. Life is calm and they are at ease with each other. Then Connell receives news that he has been offered a place to study in New York. Neither of them know how to process the news and so they decide to let it sit.
