"There isn’t much in the way of plot. This is, above all, a mood piece. As with life, there is no dramatic or Damascene moment for Nicola – just a cumulative pressure, a coded message from a friend, a gradual admission that the scales of happiness are unignorably tipped. There is no neat resolution, but when Nicola finally leaves to spend a night at her mum’s (she had intended to leave for good, but Adam hints at suicide, so it is whittled down to a week and then a bare 24 hours), we see her walk across the family garden and smile. From the grin alone we may infer liberation.
If you see yourself in any of it, listen to the alarm bells. When did you last smile freely?".
