An Island off the coast of Ireland, recently purchased and renovated, is the setting for an elite wedding. The guests arrive, boating across the choppy sea. A storm is in the air. This is supposed to be the happiest weekend of their lives, but it is anything but. As the weekend progresses, guests reveal more about their pasts. Everyone is connected, and no one has forgotten what's happened. The wedding is perfectly planned, not a thing could go wrong. Until someone dies, that is.
