Cillian Murphy stars in this bittersweet drama set in a well-heeled corner of Dublin.

The lives of two dinner-party-throwing couples (Murphy, Eva Birthistle, Catherine Walker and Andrew Scott) come messily unstuck.

Making his film-directing debut, playwright Mark O’Rowe shows that it takes very little for these marriages to fray and unravel. ‘Our happiness is fragile,’ says Walker, embarking on a passionate liaison with Murphy. ‘We’re all hanging on to it by the skin of our teeth.’

To tell the truth, there’s something a tad stagy about O’Rowe’s handling of his story, but the quality of the performances makes it compelling viewing all the same.
