Emma and Julian are in their 30s and don’t know what is next in their lives. A miscarriage has shaken them both and splintered them in different directions, though the long-term couple doesn’t know that yet. So, like many well-to-do thirtysomethings, they leave their home in London and head for the sunnier climes of Greece to house-sit for a friend.
It’s there that Emma suggests shaking up their relationship by opening it to other people: she wants to watch Julian sleep with another woman. He’s hesitant but he loves her, so he goes along with it. Enter Lena, a decade-younger Greek woman Emma meets at a bar. Naturally, the interloper complicates things.
