At his friend Iris's suggestion, Jack, who is not coping well with his brother's death, goes to her father's island cabin to sort things out. He is surprised to learn that Iris's lesbian sister Hannah has broken up with her partner and that she has been staying at the cabin for some time. After a night of drinking, Hannah and Jack end up having sex. The next day, to their surprise, Iris arrives at their cabin. She confesses to Hannah that she secretly has feelings for Jack. Meanwhile, Jack finds out that Hannah, who has been trying to get pregnant, supplied him a condom with holes the night they had sex. The rest of the movie deals with how the mix-up affects the relationships between Jack, Iris and Hannah.
Best part of story, including ending:
The relationship between two sisters is depicted realistically in this movie. Also, the dialogues don't sound forced or contrived, but flow naturally.
Best scene in story:
The scene where two sequences are shown simultaneously - Hannah confessing to Iris that she slept with Jack, and Jack finding out that the condom he and Hannah had used was full of holes - is both funny and heartbreaking.
