A bitter housewife sets up a meeting with the young woman she suspects of having an affair with her husband. The consequences are deadly.
Unsavoury slice of middle class discontent, with a nice twist. I think I saw this when it originally aired, remember being very impressed by the girl in the red swimsuit. But the praise goes to the lead actress, who does a good transformation from resting-bitch-face to sour glamour puss, recognising she's been cheated of life in many ways. Also to her sidekick, who does a nice comic turn as a drunk.
It's brief, so I don't agree with the criticism of dull domesticity - the dialogue effectively sums up the hopelessness of the characters without preaching, and the performances are well tuned.
