Jack, struggling emotionally a year after the death of his brother, takes up an offer from his friend (and his brother's ex-girlfriend) Iris to stay at her father's isolated island cabin, to contemplate and restore his spirits. Once he arrives there by ferry and then bicycle, Jack unexpectedly encounters Iris's sister Hannah, a lesbian who has recently broken up with her partner and has moved to the cabin without letting her family know. Although she initially attempts to attack him as a trespasser, he explains his relationship to Iris and she allows him to stay.
