It's Breda's birthday, but life's not been going according to plan of late and she's in no mood to celebrate. Her department at work is downsizing leaving her to reapply for her own job, her husband's just left her for another woman and she's too frightened to get on a plane to visit her only child, Colm. However, her friends Marie, Irene, Ursula and Marie's daughter, Clare, have gate crashed and they've bought cava, Bacardi and a rather disgusting 'health' cake. As the night wears on however, Breda's mask of faux happiness begins to slip.
