Two years after being driven apart by a family tragedy, former couple Will and Eden are reunited at a dinner party hosted by Eden and her current partner David. Joined by his new girlfriend and half a dozen old friends, Will finds it hard to settle into the evening's seemingly forced festivities, a feeling not helped by Eden's erratic behaviour. As the strange soiree progresses, Will's anxieties begin to grow, until he realises the real reason they have all been brought together. At once a playful lesson in tension building and a quietly devastating portrait of grief and loss, Karyn Kusama's teasing chamber piece is a perfectly pitched exercise in discomfort. Aided by uniformly excellent performances from the cast, Kusama maintains a vice-like grip on her material, cranking up the suspense with obvious glee, all the while keeping things grounded with an inescapable sense of sadness.
